摘要
提出了基于转换量测的IMM雷达伺服系统变结构控制方法,一方面用该算法对输入信号进行滤波降噪,消弱了伺服系统的抖振;另一方面利用算法估计的目标角速度、角加速度状态,减小了伺服系统动态滞后。仿真验证了该算法的有效性。并在实际工程应用中取得了良好的控制效果。
By using the estimation of parameter in object movement,this paper presents variable structure control,based on IMM of servo system tracked by radar.The algorithm filters the wave of controlled input signals,to decrease the effects which noises does to servo system,and to reach the purpose of diminishing the buffeting.By making use of target angular speed and the state of angular acceleration which are estimated by algorithm,it can reduce the dynamic hysteresis of servo system.This paper gives the simulation of MALAB,validates the feasibility of the method and obtains good control effect.
