速度/加速度误差补偿对光电跟踪系统稳定性影响分析

Stabilization Influence Analysis for Velocity/Acceleration Error Compensation of Photoelectric Tracking System

高速高精度光电跟踪控制系统采用速度/加速度误差补偿控制策略后,虽降低了系统跟踪误差,对系统稳定性有所影响,但提高了系统跟踪精度。通过Matlab对比加入速度、加速度误差补偿控制策略前后,在提高光电跟踪系统跟踪精度的同时,虽然系统稳定裕度有所降低,但恰当选择参数对系统稳定性几乎无影响。

High speed and precision track control system adopts velocity/acceleration error compensation control. Although system track error and stability are reduced, the system track precision is improved. Through comparing entrance velocity and acceleration error compensation control strategy, the photoelectric track precision is improved. Although the system stability is reduced, if choosing propriety parameter, hardly affect the system stability.
