| Description |
Basic concepts of open loop and closed loop control. System modelling, block diagrams, signal flow graphs, transfer function, and state space representation. Concepts of controllability, observability, minimality, stability, and sensitivity. Time domain and frequency domain analysis of control systems. Stability analysis using Routh-Hurwitz, Nyquist and root locus methods, phase margin, Gain margin. Compensator design using frequency domain and time domain methods like root locus, Bode plots, pole placement in time and frequency domain. Asymptotic observers. |
