PID Enhancements

Commercial proportional-integral-derivative (PID) controllers generally have many features beyond the simple control algorithm. All have antireset windup capability and many have automatic tuning and gain-scheduling functions. The objective of this chapter is to provide an overview of the common techniques used.

After studying this chapter the reader should be able to:

11.1 Background

11.2 Antireset Windup

11.3 Autotuning Techniques

11.4 Nonlinear PID Control

11.5 Controller Parameter (Gain) Scheduling

11.6 Measurement/Actuator Selection

11.7 Implementing PID Enhancements in SIMULINK

11.8 Summary

11.1 Background

The focus of the techniques developed thus far in this book has been on linear systems, although it is ...
