Method of tracking and aiming in optoelectronic system on airborne uncontrolled firepower

Under the condition of airborne uncontrolled firepower, the parameter requirements which affect the tracking and aiming of moving targets were analyzed. Through the establishment of a stable control architecture model based on a fast mirror, many error factors such as optical image error, load vibration stress error, dynamic response lag error, friction torque interference error, mechanical structure error and electrical error affecting the aiming accuracy were specifically elaborated, and the optical image error, load vibration stress error and dynamic response lag error were compensated and simulated by Matlab/Simulink. The simulation results show that the closed-loop bandwidth, stable tracking accuracy, and timeliness performance of tracking and aiming conversion of the control system are good, which theoretically proves the effectiveness of this tracking and aiming method.
