遥控武器站跟踪线隔离连续射击扰动分析

Research on Line-of-Sight Isolating the Disturbance from Fusillade for Remote Control Weapon Systems

根据跟踪线和火力线方位共轴的遥控武器站的架构特点,分析连续射击的冲击力对跟踪线产生的扰动的动力学特性,提出了电机控制回路耦合扰动的概念。通过对比分析图像闭环和内环稳定2种模式的隔离扰动性能,设计了将光纤陀螺作为反馈器件的内环稳定控制器隔离射击扰动并获取足够带宽,有效降低了射击扰动对跟踪线跟踪精度的影响。根据分析结果,设计了图像闭环和内环稳定2种隔离模式的SIMULINK仿真模型,仿真结果表明,内环稳定模式能提高隔离扰动的性能。

On the basis of the systematic characters of remote control weapon systems （RCWSs）which is the line-of-sight and line-of-fire azimuth coupling together,an analysis of the dynamics of disturbance gen-erated by the wallop is shown,and a concept of disturbance coupled by motor control loop is proposed. Based on the analysis of comparing the performance of isolating the disturbance of image close loop mode with inner loop stable mode,the inner loop controller of inner loop stable mode is designed to isolate the disturbance and obtain the sufficient bandwidth with the FOG feeding back the velocity.And then the tracking error generated by fusillade can be availably reduced.Finally,the SIMULINK model of image close loop mode and inner loop stable mode is designed.The result of simulation verifies that inner loop stable mode can improve the performance of isolation.
