射电望远镜PID控制系统仿真

射电望远镜控制系统是射电望远镜设计中的重点,控制系统的控制精度直接影响到射电望远镜的测量精度和灵敏度.通过对射电望远镜系统建模分析,发现传统的PID算法存在积分饱和缺陷问题,会造成系统超调,调节时间延长等不利结果.将积分分离PID控制算法引入到射电望远镜控制器设计中,利用LabVIEW实时仿真模块的功能,搭建了半实物仿真模型,分别采用传统PID和积分分离PID控制,对系统进行半实物仿真实验,提高控制器的控制性能,实验结果表明,积分分离PID控制效果良好.

Simulation of Radio Telescope PID Control System

Control system is an important part of radio telescope,and the accuracy of the control system directly affects the measuring accuracy and sensitivity of radio telescope.The radio telescope system modeling analysis shows that the General PID(Proportional-Integral-Differential) algorithm has the defects of integral saturation,thus resulting in system overshoots,extending regulation time and so on.Integral separation will be introduced to the PID control algorithm in radio telescope controller design.Based on ...
