变结构天线伺服跟踪控制技术

Servo Tracking Technology Based on Variable Structure PID Control

天线伺服跟踪控制常用的经典PID(Proportion Integral Differential,PID)控制算法中,存在系统的跟踪精度与稳定性的矛盾。将自动控制理论中变结构控制器的思想运用在经典PID控制算法中,设计了一款变结构PID控制器以改善天线伺服跟踪系统的控制效果,并在实践中与经典PID控制的控制效果进行对比,证明了变结构PID控制算法的有效性。

There is a contradiction between tracking accuracy and stability in the classical Proportion Integral Differential(PID)control algorithm commonly used in antenna servo tracking control.The idea of variable structure controller in automatic control theory is applied to the classical PID control algorithm,and a variable structure PID controller is designed to improve the control effect of antenna servo tracking system.In practice,the control effect is compared with the classical PID control,and the effectiveness of the variable structure PID control algorithm is proved.
