Predictive Control Approaches for PID Control Design and Its Extension to Multirate System

Part of the Advances in Industrial Control book series (AIC)

Abstract

Proportional-Integral-Derivative (PID) control is the most widely used control method. Since, PID control performance can be adjusted by tuning the PID parameters, the selection of the PID parameters is very important, but optimal PID parameters are not easily obtained. Advanced control has high potential, but on-site engineers prefer PID control to advanced control. Hence, advanced control needs to be achieved by PID control.

In this chapter, generalized predictive control (GPC) is attained by PID control. First, the technique that GPC law is approximated by a PID control law is introduced. Next, the obtained GPC-based PID control is applied to a weigh feeder. Finally, the design method of a GPC-based PID control system is extended to a multirate system in which the sampling interval is an integer multiple of the update interval.
