For heavy load,big friction and high tracking accuracy requirement of the high performance opto-electronic tracking platform,the servo control strategy based on composite control was proposed.The linear quadratic optimal feedback controller with disturbance observer was designed for speed loop,and the zero phase error tracking controller(ZPETC) was added in the forward channel,which improve the tracking performance of speed loop,and position loop uses PID nonlinear feedback control mode to reduce overshoot and improve the steady accuracy;the given position information of low rate is interpolated and filtered respectively,and through a high gain differentiator and Kalman predictive filtering,the turntable speed and acceleration are predicted and estimated to realize complex control.The experiments have proved that this strategy can effectively improve the tracking accuracy under high acceleration.
