针对激光跟踪系统对目标位置难以快速准确跟踪控制的问题,在信号接收处理中采用插值法和传统算法相结合进行数据处理;在伺服跟踪机构中,基于Lyapunov稳定性理论利用系统输入和输出量设计模型参考自适应控制系统,并在无干扰和有界扰动两种情况下进行MATLAB仿真;并搭建系统进行实物虚拟实验。实验结果表明:与常规控制算法相比,该控制算法在信号接收处理中具有误差小和计算速度快,在对目标的跟踪中具有动、静态误差小,响应速度快的特点,且对系统中各种干扰有较好的抑制,表明了该控制算法能够满足激光跟踪系统对目标位置跟踪控制要求。
Aiming at the problem that the laser tracking system can not accurately and quickly track the target position, the interpolation method and the traditional algorithm are used in the signal receiving processing to process the data. In the servo tracking mechanism, the system input and output design based on the Lyapunov stability theory Model reference adaptive control system, and in the case of non-interference and bounded disturbances MATLAB simulation; and build the system for virtual experiments. The experimental results show that compared with the conventional control algorithm, the control algorithm has the advantages of small error and fast calculation speed in the signal receiving process, small moving and static errors and fast response in the tracking of the target, All kinds of interference have better suppression, indicating that the control algorithm can meet the laser tracking system on the target position tracking control requirements.
