Course Outcomes At the conclusion of the course, students should have the following competencies:

1. Knowledge of the time-domain analysis methods including root-locus and significance of dominant pole-zero concepts in the analysis of linear continuous time control systems. (a,c,e)

2. Ability to design PID control systems using time-domain methods and write design reports. (a,c,e,k)

3. A clear understanding of frequency-domain analysis tools based on Bode, Nyquist, and Nichols plots in the analysis of feedback control systems. (a,c,e,k)

4. Ability to design Phase- Lead, Phase-Lag, Lag-Lead compensators using frequency domain methods for continuous-time control systems and write design reports. (a,c,e,g,k)

5. Understanding of state variable representations and state feedback for control systems. (a,c,e,g,k)

6. Hands on experience on the use of computer tools of MATLAB and SIMULINK in the analysis and design of control systems. (a,c,e,g,k)

Computer Usage Four computer projects are assigned on the College Computer Network (MOSAIC) for analyzing and designing control systems utilizing both time

domain and frequency domain methods using MATLAB and SIMULINK software. Fifth computer project is assigned for the analysis of a control system in the state variable form. These are individual projects. The projects are used to assess the outcomes and course goals.

Laboratory The newly developed control systems laboratory is required to provide hands on experience of implementing control systems on four different experimental systems.

Design Content The course is heavily design oriented and the analysis tools are developed to help students in the design of controls systems. The course is approximately seventy five percent design and computer tools are heavily emphasized.

Grading * The final grades are assigned based on the following grading scheme: Test 1: 25%, Test 2: 25%, 5 Projects: 25%, Final Exam: 25%.The homework is only considered for marginal cases.

* Grading policy may be modified by the instructor for each section of the course.

Follow-On Courses This course is a prerequisite for the second course on controls (ECGR 4112) which emphasizes Digital Control Systems.

University Policies and Information

The following statements are provided to ensure compliance with federal regulations and SACS standards, as detailed in http://legal.uncc.edu/legal-topics/classroom-policies-and-practices/suggested-standard-syllabus-policies#disability.

• Code of Student Academic IntegrityStudents have the responsibility to know and observe the requirements of the UNC Charlotte Code of Student Academic Integrity. This code forbids cheating, fabrication or falsification of information, multiple submission of academic work, plagiarism, abuse of academic materials, and complicity in academic dishonestly. Students are expected to submit their own work, either as individuals or contributors to a group assignment.Faculty may ask students to produce identification at examinations and may require students to demonstrate that graded assignments completed outside of class are their own work. Violations of the Code will result in disciplinary action.

• Code of Student Responsibility

Students are expected to uphold the University’s Code of Student Responsibility. The purpose of the Code is to protect the health, safety, welfare, and property of the campus community; foster the personal, social, and ethical development of members; provide an environment conducive to learning; and encourage and create a community that values scholarship, integrity, respect, accountability, dignity, honor, compassion, character, and nobility. Violations of the Code will result in disciplinary action.

• Rights and Responsibilities in Obtaining Disability Accommodations:Students with disabilities may qualify for special academic accommodations. Students are encouraged to consult with the Office of Disability Services prior to the beginning of the semester to understand their rights and follow policies and procedures.

• Definition of a Credit HourTo ensure compliance with the federal and SACS definition a credit hour, the following examples are provided.

◦ A 3-credit course requires three hours of classroom or direct faculty instruction and six hours of out-of-class student work for the equivalent of approximately 15 weeks. Out-of-class work may include but is not limited to: required reading; homework; studying for quizzes and exams; research; written assignments; and project design, simulation, testing and demonstration.

◦ A 1-credit laboratory course requires 2.75 hours of classroom or direct faculty instruction and 2 hours of out-of-class student work each week for approximately fifteen weeks. Out-of-class work may include but is not limited to: required reading, library research, laboratory preparation, and preparing lab reports. *May be modified to accommodate varying credit hours or instructor expectations.

Notes This is an elective course and is required for those students who have opted for Control Systems Concentration.
