Abstract:For the photoelectric system tracking target and the problem of insufficient tracking accuracy of the electro-optical system when servo subsystem using traditional feedback control, the control principle, modeling and simulation are analyzed, a suggestion that use the compound control method to improve the tracking accuracy of the system is presented in this paper. In the practical system, Using filtering prediction technique to predict the target position after the synthesis and then predicts the angular velocity and angular acceleration of the target. The angular velocity and angular acceleration of target are derived directly from the target model in this simulation which simplified the simulation model. And finally the simulation results show that the compound control can improve the tracking precision of the photoelectric system.
