Motivation
Automatic Control course aims to provide an understanding of the principles of dynamic modeling and controller design for mechatronic systems. The concept of feedback control is very wide and applies to many fields ranging from robotics and manufacturing to autopilots, disk drives and even economical or biological systems.

Course Outline
The following topics are covered in the course:

1. Introduction: Control systems, Open-loop control systems,Closed-loop (feedback) control systems, Basic control problems, General design objectives.
2. System Representation: Mathematical modeling of dynamic systems, Laplace transform, System transfer functions, State space model, Block diagrams, Reduction of block diagrams, Flow graph, Mason rule.
3. Time Response of Dynamic Systems: First-order system response, Second-order system response, Higher-order system response, free & forced response of systems.
4. Stability Analysis: Phase-portrait of a system, BIBO stability, Routh - Horwitz stability criteria.
5. Feedback control: Steady-state errors, Root locus, Process control, Ziegler-Nichols compensation.
6. Frequency Response Analysis: Bode plots, Nyquist methods, Compensation using Bode plots, Gain margin, phase margin.
