摘要
在分析智能积分器和非线性比例积分微分的控制特点基础上,针对雷达伺服系统工作需求,研究一种非线性控制器设计方法,探讨了控制器的参数整定过程。这种非线性控制器利用了非线性变化特性,解决伺服系统跟踪的快速性和平稳性问题。仿真和实践表明,这种非线性控制提高了雷达伺服系统的跟踪性能,减小雷达伺服系统跟踪过程的加速度滞后误差(动态滞后)。非线性控制器结构简单,运算方便,调整参数少,易于整定,有利于工程实践。
Based on the analyse of the control characteristic of intelligence integrator and non-linear PID controller,and aiming at the demanding of the radar servo system,it researches a non-linear controller（NPII）,and discusses the adjusting process of the controller parameters.By using the characteristic of non-linear change,the NPII Controller resolves the high-speed and stability of the servo system.Simulation and practice show that non-linear control can improve the tracking precision and reduce the dynamic lag errors of the radar servo system.The NPII controller has the simple structure,convenient operation,a few adjusting parameters,and adjustable easily.It is propitious to carry out engineering.
