基于Simulink环境下的船载雷达伺服系统PID参数整定

摘要

针对PID参数复杂繁琐的整定过程这一问题,提出了基于MATLAB/Simulink仿真环境,模拟工程稳定边界法的船载雷达伺服系统PID参数整定策略和步骤,并进行了仿真实验.结果表明该方法具有良好的收敛性,使得控制系统动态性能得到有效改善,并且很大程度上减少了工作量.%This paper expounds the structure and principle of shipboard radar servo system,according to traditional PID parameter tuning problem,the parameter self-tuning fuzzy PID control technology is applied to the servo system position loop,through the simulation experiments show that the method can 't depend on the mathematic model of the system,and according to the relation between input and output of the PID parameters on-line adjustment,automatic adjustment loop bandwidth,increase the system dynamic performance and steady performance,strong robustness and adaptability.
