ECE 3510 - Introduction to Feedback Systems

Laplace transforms, boundedness and convergence of signals. Transfer functions, stability, steady-state and transient responses, effect of initial conditions, state-space representations. Feedforward and feedback control, steady-state error and integral control, Routh-Hurwitz criterion, root-locus method, application to phase-locked loops. Bode plots, Nyquist criterion, gain and phase margins. The z-transform and the analysis of discrete-time signals and systems. Sampled-date systems, conversions between continuous-time and discrete-time systems.
