Chapter 11. PID Enhancements

Commercial 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. The major sections of this chapter are as follows:

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
