摘　　要：由于被跟踪目标的飞行速度不断提高,靶场光电跟踪伺服系统的输入角速度、角加速度在逐步增加,导致系统跟踪动态误差加大,甚至出现目标逃逸出光学探测器视场的情况。对此,采用最小二乘预测滤波算法,通过将电视或红外脱靶量叠加转台角位置信息,估计出目标角速度值,前馈到伺服角速度环输入端,从而构成等效复合控制。经过仿真和跟踪旋转靶标试验验证,所提方法可以计算出相对精准的目标角速度,采用等效复合控制可以有效减少跟踪误差,提高跟踪精度。Due to the increase in the flight speed of the tracked target,the input angular velocity and angular acceleration of photoelectric tracking servo system in the shooting range are also gradually increasing,resulting in an increase in the dynamic tracking error of the system,and even the situation of escaping from the detector field of view has occurred.Therefore,the least squares prediction filtering algorithm is adopted to estimate the target angular velocity by superimposing the television or infrared off target distance with the turntable angular position information,and feed it forward to the input of servo angular velocity loop,thus forming an equivalent composite control.Through simulation and tracking the rotating target experiment verification,this method can obtain relatively accurate target angular velocity,using equivalent composite control can effectively reduce tracking errors,and improve tracking accuracy.
