20801857 - BASICS OF AUTOMATICS

Develop an understanding of the elements of classical control theory. In particular understand: the concept of feedback and its properties; the concept of stability and stability margins; and the different tools that can be used to analyze the previous properties. Finally gain a working knowledge of the basic linear control design techniques.
