Instructor: Prof. S.D. Agashe, Department of Electrical Engineering, IIT Bombay.
The course deals with topics in control systems: industrial control examples and modern control problems; basic characteristics of feedback control systems - stability, steady-state accuracy, transient accuracy, time response of second-order systems, steady-state errors and error constants; frequency response analysis - the relationship between time and frequency response, Polar plots, Bode plot, stability in the frequency domain, Nyquist plots, Nyquist stability criterion; State variable analysis - state variable, state model, state models for linear continuous-time functions; introduction to optimal control and nonlinear control.
