Realization of the PIP Controller for Processes with Long Time varying Dead Time

A process with long varying dead time is always difficult to be controlled.This paper introduces the principle of the PIP control in which the influences of long dead time on control systems have been eliminated.A method of dynamic changing the sampling period to simulate the dead time according to its magnitude is presented for the realization of the PIP controller with varying dead time,and recursive formulas are given.Simulation results show that the method has an excellent control performance and the advantages of simplicity and practicability,and is easy to be used in microcomputer.
