Introduction: Automatic control, feed forward and feedback.

Models of Dynamical Systems: For linear electrical and mechanical systems, block schemes.

Analysis of Linear and Stationary Systems: derivation of system equations, standard models; time domain specifications, transfer function, Laplace transform, poles and zeros.

Basic Properties of Feedback: gains, static properties (e.g., reducing system steady state error to disturbances), dynamic properties (e.g., enhance system dynamics, stabilize an unstable system, make unstable a stable system), reducing system transfer function sensitivity to parameter variations, speeding up transient response.

Frequency Response Design Method: Fourier Transform, Nyquist Stability Criterion, Stability margins, Bode’s Gain-Phase relationship, lead-lag compensation, specifications in terms of the sensitivity function, obtaining a Pole-Zero Model from Frequency-Response data.

Digital Control: Dynamic analysis of discrete systems, design using discrete equivalents, sample rate selection.
