摘要
介绍旨在消除大纯滞后影响的PIP控制器的基本原理.针对大时变纯滞后的PIP控制器的实现问题,提出了一种根据变纯滞后的大小而动态改变采样周期来模拟纯滞后时间的方法,并给出了递推公式.仿真结果表明,这种方法对大时变纯滞后的对象具有优良的控制性能,并且简单、实用、易于在微机上实现.
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.
