Frequency-domain techniques: Root-locus methods, Frequency responses, Bode-plots, Gain-margin and phase-margin, Nyquist plots, Compensator design: Proportional, PI and PID controllers, Lead-lag compensators.
State-space concepts: Controlability, Observability, pole placement result,
Minimal representations.
