Learning Outcomes
1. Understanding of the structural elements of an automatic control system and the objective of the control design. Learning, understanding and computing of the different representation forms of dynamical systems, particularly using differential equations and transfer functions.
2. Learning and computation of analysis and synthesis tools of a control system, i.e. block diagram representations, Bode diagrams, Nyquist criterion, and Root locus contours.
3. Learning and understanding of the design specifications and criteria
4. Learning and application of different control design approaches and specifically, of the three term controller (PID) and the Lead/Lag controllers.
