Control System The central goal of control engineering is

the design of a technically feasible way to act on a given process so that it behaves in a prescribed manner.

The desired behavior should be achieved as closely as possible in the presence of uncertainty in the process (modeling error) uncontrollable external disturbances acting on

the process (process and measurement noise).

23

Idea of Feedback Compare actual behavior with desired

behavior Take corrective action based on the

difference Deceivingly simple idea, but very

powerful concept Feedback is a key idea in control

Control SystemM. B Hoagland and B Dodson. The Way Life Works. Times Books, 1995

‘Feedback is a central feature of life. The process of feedback governs how we grow, respond to stress and challenge, and regulate factors such as body temperature, blood pressure, and cholesterol level. The mechanisms operate at every level, from the interaction of proteins in cells to the interaction of organisms in complex ecologies.’

Branches of Control Systems Linear Non Linear Multivariable Robust Adaptive Fuzzy Intelligent Networked

33

Control ObjectivesTwo broad classes of control problems

The regulator problem: Controlled output is held as close as possible to a constant setpoint, despite disturbances

Control of basis weight and moisture on paper machine

The servomechanism or tracking problem: Controlled output follows as closely as possible a time-varying command, despite disturbances

Tanker autopilot, radar tracking device
