Introduction to feedback
Section four: Introduction to PID
This chapter is on the theme of linear feedback control, for example with G(s) representing a system, M(s) a compensator and d an input disturbance signal:
This section focuses on an introduction to the concepts of PID compensators. What is a PID? Why is is popular? Simple tuning rules and numerical examples.
