[Abstract]:Airborne photoelectric turret system is a multi-degree of freedom high-precision servo control system. It is capable of fast tracking, large range tracking, searching, capturing, tracking and aiming at the target in the detected area with high precision. It can provide high precision and high resolution external environmental information for the aircraft, and can be used for situational awareness and command decision. The gyroscope stability mathematical model of two axes and two frame airborne photoelectric turret system in azimuth and pitch and the coupling relationship between them are established. The joint simulation model of airborne photoelectric turret system with two degrees of freedom in azimuth and pitch is built. In the environment of MATLAB simulation, the whole system joint simulation is carried out for different external input environment and simulation environment of aircraft attitude change disturbance. The simulation characteristics of the system are analyzed. The simulation results show that the model is reasonable, the system can respond quickly and adjust stably, and has high precision of gyroscope stable servo control.
