摘要
常采用的双闭环控制方法无法解决动机座下的光电跟踪设备其跟踪精度与稳定性的矛盾,而导致跟踪失败。本文对平台罗经角度数据进行速度数学建模,首先通过有限记忆最小二乘滤波得到速度的平滑数据;再进行动机座下的坐标变换和视轴校正;最后将平滑的速度数据通过复合控制前馈到速度回路;试验表明:提高了精度了同时,保证系统的稳定性,其有效隔离度为13.06,大大提高了设备的跟踪性能。
It does not resolve the contradiction of tracking precision and the stability under the optoelectronic tracking system by using the method of double closed loop,and that it leads to tracking faihure. First the smooth speed data are get with Limited Memory Least Square filter; then the coordinate transformation and the LOS revising are carried through under the dynamic platform; the end the smooth data are entranced the speed loop by compound control, examination indicated that it inproves precision, ensures stability of system, the isolation degree is 13.06dB. The methods enhance the tracking precision of the optoeleetronic tracking system.
