噪声是光电跟踪系统的一个关键问题。分析了影响光电跟踪系统跟踪性能的两种主要噪声-脱靶量噪声和力矩波动引起的噪声
及其与闭环带宽的关系。从抑制噪声的角度综合给出了速度回路和位置回路带宽的设计策略。分析表明
高的速度回路和位置回路带宽有利于抑制力矩波动引起的随机噪声
而对脱靶量噪声而言
低位置回路有利于对该噪声的抑制。进一步分析表明
力矩波动主要对速度回路的影响较大
也主要靠速度回路来抑制。力矩波动引起的随机跟踪误差比脱靶量噪声引起的随机跟踪误差小一个数量级
约为后者的1/6~1/10。因此在设计位置回路带宽时
可以不考虑力矩波动的影响。
Random noise is one of the key problems in the optoelectronic tracking systems. Two kinds of primary noise affecting the tracking performance-the noise of tracking error and the noise caused by momentum fluctuation and their relationship with the closed bandwidth are analyzed. Then the design strategy of the bandwidths of the velocity loop and the position loop are discussed. The analysis results show that the higher bandwidths of the velocity loop and the position loop are favorable to restrain the random the noise caused by momentum fluctuation. While it’s just reverse to the random noise caused by tracking error. Further analysis shows that the magnitude or the power of the output noise produced by the momentum fluctuation is lower than that caused by the tracking error by a quantitative level
about 1/6~1/10 of the latter
So the noise of momentum fluctuation can be ignored in the decision of the control bandwidth.
