Brief History of the InternationalTelecommunications Energy Conference (INTELEC)

2011 IEEE PELS Distinguished Service Award

In May 1975, Messrs. N. Osifchin, B. J. Yokelson, and the late J. J.(Joe) Suozzi of Bell Telephone Laboratories developed the idea of an international conference on telephone energy systems. During visits to England, Sweden, Holland, France, Germany, and Italy to

discuss power for telecommunications, the idea of an internationalconference on telecommunications energy was discussed andgained favor with telecom administrations. IEEE COMSOC agreedto sponsor the conference and the first INTELEC was scheduled forOctober 25–27, 1978, in Washington, DC.

At the time the conference was called “The International TelephoneEnergy Conference” from which the term “INTELEC” was derived. In1979 the name was changed to “The International Telecommunica-tions Energy Conference,” and the term “INTELEC” was retained.

During 1977 and 1978, plans were being drawn to form a govern-ing body for the conference. This was accomplished by 1978 with theformation of an INTELEC Advisory Committee, representing the worldcommunity and presided over by N. Osifchin. The first Advisory Com-mittee meeting was held in October 1978, at the first INTELEC confer-

ence and an immediate debate arose as to how often the INTELEC con-ferences should be held. A second INTELEC conference was plannedfor November 1979 and was chaired by W. M. Miller (Lorain Products). A Planning Committee (later to become the Conference ExecutiveCommittee (CEC)) was mandated to prepare recommendations on thefrequency and plans for future meetings. Joe Suozzi was appointedto write a Constitution and the Bylaws for the INTELEC organization.

The second INTELEC conference was held with an even moreenthusiastic turnout than the first and then plans began to be developed for the first INTELEC conference outside of North America,in London, England in May 1981, with Ian White of the British PostOffice as Chairman. The success of the 1981 meeting led to the ac-ceptance of the concept of an annual INTELEC conference.

By 1986, the international character of the INTELEC conference

was ensured by constitutional changes providing for a 50%-50% American and non-American balance of Advisory Committee mem-bership and by acceptance of a six-year cycle with three meetings inNorth America, two in Europe, and one in Asia.

In 1991, negotiations among COMSOC, INTELEC and the recentlformed IEEE Power Electronics Society (PELS) resulted in an agreement to transfer sponsorship of INTELEC from COMSOC to PELS where it joined the Applied Power Electronics Conference (APEC

and the Power Electronics Specialists Conference (PESC), which aralso sponsored by PELS.

Over its history, INTELEC conferences have been held in Washington, London, Tokyo, New Orleans, Munich, Toronto, Stockholm, SanDiego, Florence (Italy), Orlando, Kyoto, Paris, Vancouver (Canada)The Hague, Boston, Melbourne (Australia), San Francisco, Copenhagen, Phoenix, Edinburgh (Scotland), Montreal, Yokohama, ChicagoBerlin, Rome, Inchon (Korea), and Amsterdam. INTELEC 2012 wibe held in Scottsdale, AZ, September 30th to October 4th. This wibe the 34th International Telecommunications Energy Conference.

After the fall of the Berlin Wall and the opening of eastern European borders, there was a strong desire to hold telecommunicationenergy conferences in Germany and Eastern Europe. In the early 90the Advisory Committee approved establishment of a smaller con

ference, the Telecommunications Energy Special Conference (TELESCON) to address this need. The first TELESCON was held in Berlinin the Spring of 1994. Additional Spring conferences took place inBudapest in 1997, Dresden in 2000, and Vienna in 2009. In additioneach year, a “Friends of INTELEC” seminar, is held in Sweden.

INTELEC and TELESCON conferences now provide a venue fotelecom, datacom, wireless and cable television operators and vendors of all types of power equipment used by these and relatedservice providers. A typical conference has technical papers and exhibits covering virtually all aspects and topics related to communications energy systems.

Since 1995, tutorial sessions have become a part of the technicaprogram. Experts in the subject matter conduct the tutorials, and attendees earn continuing education credits. Future conferences wi

undoubtedly cover new technologies to meet the evolving needs othe industry.

The PELS community has overwhelmingly supported ChristopherRiddleberger’s nomination for the 2011 IEEE PELS DistinguishedService Award. As much as he deserves this prestigious award forhis impeccable service record spanning more than 32 years, Chrishas graciously informed us that he had won the same award in 2005

and in accordance with IEEE guidelines this award can only bemade once to an individual.But in the heart of many of our members, Chris is a true winner

not only for his distinguished services for the society but also for up-holding of IEEE’s standard on integrity and honor to its highest level.The PELS AdCom sincerely wishes to apologize to our members andChris himself for overlooking this detail in the award nominationprocess.

Furthermore, PELS AdCom has decided to present to Christo-pher O. Riddleberger the Certificate of Appreciation for Life-long Volunteer Contributions to the IEEE Power Electronics Society and the International Telecommunications Energy Conference(INTELEC®).

The certificate was presented on November 19, 2011 to Chris by the PELS President, Dushan Boroyevich, INTELEC® Representatives

President Barack Obama has awarded theNational Medal of Technology andInnovation to PELS member Dr. B. JayantBaliga.

Baliga was honored for inventing, de- veloping, and commercializing the Insu-

lated Gate Bipolar Transistor (IGBT). TheIGBT improves energy efficiency by morethan 40 percent in an array of products,from cars and refrigerators to light bulbs,and it is a critical component enablingmodern compact cardiac defibrillators.The impact of the improved efficiency of IGBT-enabled applications has beena cumulative cost savings of $2.7 trillionfor U.S. consumers and $15.8 trillion for worldwide consumers over the last 20 years. At the same time, theimproved efficiency produced by IGBT-enabled applications hasproduced a cumulative reduction in carbon dioxide emissions of 35 trillion pounds in the U. S. and 78 trillion pounds worldwide

over the last 20 years. In addition, IGBT-based compact portabledefibrillators are projected to have saved nearly 100,000 lives inthe United States.

The medal, which is awarded annually, recognizes outstanding contributionto America’s economic, environmental andsocial well-being. Established by the Stevenson-Wydler Technology Innovation Act o1980, the medal was first awarded in 1985.

Baliga, who has been a faculty member at NC State University since 1988, is member of the National Academy of Engineering and a Fellow of the IEEE. Prior tojoining NCSU, he was manager of the De vice Group at the Corporate Research anDevelopment of General Electric CompanySchenectady, NY. In 1983, he received theGE Coolidge Fellow Award. In 1991, he warecipient of the IEEE PELS Newell Awar

and in 1998 he received the IEEE Lamme Medal for the Invention othe IGBT. Dr. Baliga published over 500 papers and several booksamong these his well-known book entitled” Modern Power Devices

With this recognition, power electronics is moving to be a top

tier technology that can be even more prominent as we move to more sustainable society. We congratulate Dr. Baliga with his liflong achievements in the area of Power electronics.

Control and Estimation Techniques of HighPower Variable Speed AC Drives – (Part 3 of 3)

VI. Adaptive, Optimaland Fault Tolerant Control A number of advanced control techniques for ac drives are sum-marized in the control tree of Fig.1. Most of the advanced controlsuse vector control in the inner loop because the drive model issimple and linear, like that of a separately excited dc motor. Adaptive control tends to adapt the drive control for plant modeland parameter variations, and makes the system response robustagainst load disturbances. The adaptive controls can generally beclassified as self-tuning regulation (STR), model referencing adaptivecontrol (MRAC) and sliding mode control (SMC) or variable structuresystem (VSS). Intelligent controls, based on AI, are generally includ-

ed in adaptive control and will be discussed in the next section. A control system can be defined as optimal (also known as model

based predictive control (MPC)), where a performance parameter,such as response time, efficiency, or energy consumption, etc. is op-timized. Often, a mathematical cost function is defined for a systemand minimized within the constraint of the state variables. The MPCcontrol has a long history, but recently, it is showing revival and a lotof promise for high performance drives (17].

Fault-tolerant control permits drive operation in a degraded modeunder certain fault conditions, instead of shutting down the drive.For example, a three-phase inverter can be operated in single-phasemode in case of a device failure, where the developed torque will beless and pulsating in nature. In case of temporary ac supply failure,the inverter can be operated in regenerative mode (if the operating

condition permits) to maintain the dc link voltage so that the controlremains healthy.

VII. Intelligent ControlIntelligent control is based on AI, which can be defined as com-puter emulation of human thinking process. The AI techniques aregenerally classified as expert system (ES), fuzzy logic (FL), artificialneural network (ANN), and genetic algorithm (GA). The ES, basedon Boolean algebra, uses hard or precise computation, whereas FL, ANN and GA use soft or approximate computation. With a controlbased on AI, a system is said to be “intelligent”, “autonomous”,“adaptive”, “self-organizing” or “learning control”. Intelligent controlcan be applied on a plant with unknown or ill-defined model. Or,the system can be nonlinear, complex, multivariable with parameter variation problem. Of course, if the plant model is available, i t canbe used for simulation study on computer, where the control can beoptimized by iteration. Although intelligent control is now in thefrontier of advanced control technology and shows a tremendousfuture promise [18], currently, high power drives hardly use thiscontrol. In this section, only FL and ANN principles and their appli-cations on drives will be discussed very briefly.

A. Fuzzy Logic Control Fuzzy control provides robus t adaptive response of a drive withnonlinearity, parameter variation and load disturbance. Fig. 18

shows the fuzzy control of a vector drive [19], where the controller observes the speed loop error ( E ), its rate of change (CE

and generates the control signal DU , or incremental torque component of current (Di *qs ) for control of speed.The control is basically nonlinear and adaptive in nature. Fig. 19 shows the membership functions (MF) of the fuzzy variables (e , ce and du inper unit form), and Fig. 20 shows the rule matrix relating thes variables. In a fuzzy controller, the variables are fuzzif ied, thcorresponding control rules are evaluated from MFs and rultable, combined, and finally defuzzified to derive the controsignal DU . It is then integrated in commonly used fuzzy P-control. It can be shown that for variable inertia load and wit

load torque disturbance, the response is deadbeat and highlrobust. Fuzzy logic has been applied on online search-basedflux programming efficiency optimization control [20], windgeneration system [21], MRAC slip gain tuning control of vectodrive [22], precision estimation of machine parameters [23], etc

B. Neural Network Control ANN is the most generic form of AI in comparison with ES, FL anGA. Basically, ANN is interconnection of artificial neurons (model obiological neurons), which are op-amp summer-like structure witusually nonlinear activation function at the output. A large numbeof feedforward and feedback (or recurrent) ANN topologies [24have been proposed in the literature, but currently, most of th

applications use the feedforward type [25]. Fig. 21 shows the structure of a three-layer feedforward backpropagation network. Thterm backpropagation comes from the method of supervised computer-based training used for the ANN shown below the figure bthe two extra blocks. A bias source is added to the hidden and output layers (not shown). The network has associative memory opattern recognition property like that of human brain. ANN basecontrol is the most important of all the intelligent control techniquesand recently, their applications have been proposed, for example, ispace vector PWM [26], delayless filtering [26], feedback signal estimation [28], FFT analysis, dynamic plant model identification, MRACcontrol [29 ], drive fault identification and fault tolerant control [30etc. Fuzzy control can be implemented by ANN through AdaptivNeuro-Fuzzy Inference System (ANFIS) [31].

three-layer feedforward ANN that has been trained to estimate feed-back signals in vector drive [28] from the machine terminal voltagesand currents (see Fig. 10) that vary widely in magnitude and fre-quency. Note that the feedfoward ANN can not perform integration(or any dynamical operation), and therefore, the stator voltages havebeen integrated (by op amps) to calculate the flux signals (c s

ds andc s

qs ) before feeding to the ANN, as shown. The inherent noise orharmonic filtering is one of the advantages of ANN.

VIII. Conclusion A brief but comprehensive review of different control and estimationtechniques of ac drives, particularly for high power drives, has beengiven in the paper. Both scalar and vector control of induction andsynchronous motor drives using voltage-fed as well as current-fedconverters are included. The discussion on scalar control mainly includes volts/Hz control and DTC control that have been used exten-sively in high power drives. However, vector-controlled drives with voltage-fed converters and sensorless estimation are given emphasis

in the paper. The control and estimation discussed in the paper cabe easily extended to other drive configurations that are not coverein the paper. Considering the present trend, it appears that sensorles vector drives with voltage-fed converters will eventually emerge auniversal drives in future. The precision online estimation of machinparameters and zero (or near zero) frequency speed or position sensorless vector control yet remain a challenge for induction moto

drives, although substantial progress has been made in this area fosynchronous motor drives. Suffice it to say that advanced control anestimation of modern high performance drives have been possiblebecause of the advent of today’s powerful DSPs and ASICs. In factDSPs and ASICs are now universally used in all types of moderndrives.The cost differential in the control of modern sensorless vectodrive and simple volts/Hz scalar control is hardly noticeable becauseonly the software is more complex in the former, whereas the controhardware essentially remaining the same. Again, considering threcent trend, a single ASIC chip controller for high performance sensorless vector drive that may include fault diagnosis and fault-tolerancontrol is not far away. Intelligent control, based on fuzzy logic anneural network, is an emerging technology that will have dominanimpact on high power drives in future.
