Sliding mode variable structure control of gyro stabilized sighting system of airborne optoelectronic pod
2008
Because the traditional controlling methods can not meet the servo tracking systempsilas demands which were the high-speed, high-accuracy and strong-robustness, the sliding mode variable structure controlling method based on proportion switch control was researched for the gyro stabilized system of the airborne optoelectronic pod. The mathematic model of the velocity loop of the systempsilas azimuth axis was constructed. The model was described and analyzed by the phase space. The switching surface and the sliding mode variable structure controller based on proportion switch control were designed. As the simulation results shown, the new method improved the rapidness and robustness of the system, compared to the traditional controlling methods.
