文中介绍了传统的PID控制原理,PID分为位置式和增量式,计算机控制是数字PID控制。一些
改进的PID控制算法是针对实际应用中的不足提出的,如积分分离式PID控制算法,抗
积分饱和算法,变速积分算法等,实际应用中,控制又分为简单PID控制和串级PID控
制,对一些典型的控制算法,选用典型控制对象用MArLAB软件进行了对应仿真。对仿
真结果进行了对比分析,说明了改进算法的作用。(This paper introduces the principle of the traditional PID control, PID into position and incremental, computer-controlled digital PID control. Some improvements in the PID control algorithm is less than the practical application of the proposed, such as discrete integral PID control algorithm, anti-integral saturation algorithm, changing integration algorithm and so on, practical application, the control is divided into a simple cascade PID control and PID control , for some typical control algorithm, selection of a typical control object MArLAB software with the corresponding simulation. The simulation results of comparative analysis carried out to illustrate the role of the improved algorithm.)
