针对防空多管火箭炮交流位置伺服系统转动惯量和负载力矩变化大等特性,设计了基于模糊滑模控制的位置控制器。利用模糊控制调整滑模切换部分的控制,使系统对内部参数变化和外部干扰等不确定项均具有全局鲁棒性。仿真结果表明该控制策略不仅保证了系统的静、动态特性,而且有效消除了系统的抖振现象。

Considering the characteristics of varied inertia moment and load moment on the AC position servo system of air-defense multiple launch rocket system (MLRS), a position controller based on fuzzy sliding mode control was designed. The fuzzy inference mechanism was utilized to adjust the switching control and to guarantee that the system was of global robustness against parameter variations and external disturbance. Simulation results show that the proposed approach can guarantee the static and dynamic characteristics, and the system chatter is reduced efficiently.
