Presents a typical examination questions for students to attempt. Covers basic analysis tools of Nyquist, Bode and root-loci and analysis of potential lead/lag compensators. Also gives a worked solution.

Presents analysis which explains the basis for the use of a 60 degree phase margin as a good target. Illustrates the limitations of this assumption through numerous examples.

Reviews the impact of lead and lag compensators and hence presents an argument for compensators which include both these components. This insight is used to propose and illustrate a simple mechanistic design procedure for lead-lag compensators, assuming that the specification includes three...
