摘要
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 difficulty existing in accurate and quick tracking and controlling of the target position for laser tracking system,interpolation and traditional algorithms are synthetically adopted in signal receiving and processing,and a model reference adaptive controlling system with input and output values is designed based on Lyapunov steady principle in servo tracking part.MATLAB simulations are carried out both under the presence of normal and bounded disturbance,and virtual experiments are carried out by building practicality system.The experimental results show the new control algorithm has the advantages of speediness and small error in signal receiving and processing and with the characteristics of small dynamic and static error and fast response in target tracking.The algorithm can also restrain various disturbances,so it can meet the demand of target position tracking and controlling for laser tracking system.
