Reduce overshoot and noise sensitivity → add D (with filtering)
If oscillatory → check phase margin and reduce aggressive gains or add lead compensator
Compensators and Controllers: Discusses the design of Lag, Lead, and Lag-Lead compensators. It also covers P, PI, PID controllers, which are essential for industrial application.
State Variable Analysis: Introduces modern control theory. It covers the state-space representation, solution of state equations, and concepts of Controllability and Observability.
Focus on Routh Hurwitz and Root Locus.
Trick: Anand Kumar often includes "Remember" boxes. Highlight these. They contain exam shortcuts.
Practice: Solve 20 numericals on Root Locus angle of departure/arrival.
