21. Similar or Different!!! • Science • Technology • Engineering

22. 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

24. Control System

25. Control System

26. Open Loop Speed Control

27. Closed Loop Speed Control

29. Control System • Terminologies • Control • Automation • Feedback • Plant • Controller • Error • Reference • Control Signal • Input • Output

30. Applications of Control System • Motors • Vehicles • Airplanes • Robots • Fault Tolerant System • Biological • Social • Ecological

31. Control System M. 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.’

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

33. Control Objectives Two 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

34. “All the effects of Nature are only the mathematical consequences of a small number of immutable laws.” • Pierre-Simon Laplace(1749-1827)
