摘要

Dual-axis tracking radar for common servo tracking accuracy and the coordination of control, to improve control precision and coordination of performance, a coordinated control of variable gain cross-coupling model is proposes.by establishing the mathematical model of two axis servo system, Based on the analysis of pitch and level of servo motor tracking error on the accuracy of radar servo system, tracking error is extended to the situation of arbitrary motion profile curve, and the cross-coupling with variable gain control algorithm is used to coordinate and control the radar servo system.The simulation results show that this method can improve the tracking accuracy and reduce system errors.%针对常见的双轴跟踪雷达伺服跟踪精度以及协调控制问题,为提高系统控制精度和协调性能,提出一种变增益交叉耦合协调控制模式.通过对双轴雷达伺服系统建立数学模型,在分析俯仰和水平伺服电机跟踪误差对整个雷达伺服系统精度的影响的基础上,将系统跟踪误差推广到任意运动轮廓曲线的情况,采用变增益交叉耦合控制算法对雷达伺服系统进行协调控制.经仿真验证,该方法能提高系统跟踪精度,减小系统误差.
