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
11.8 Summary
