摘要
舵机加载系统主要用于模拟导弹在飞行过程中舵面受到的各种气动力矩,但存在力矩效率低,多余力较多,干扰复杂等特点。为使电动加载系统的仿真度和力矩精度进一步提高,采用自适应滑模控制对多余力矩和其他位置干扰进行抑制,同时对滑模控制的切换函数进行改进,以削弱系统存在的抖振。仿真结果显示,加载系统的精度和抗干扰能力有进一步提高。
The steering mechanism loading system is used to simulate various aerodynamic torques that the missile rudder suffers from flying,but it has some characteristics,such as low efficiency,much redundant torque and complex disturbance.In order to improve the precision and reliability of the steering mechanism loading system,adaptive sliding mode control was used and the switch function of sliding mode control（SMC） was modified to weaken system chattering.The simulation result indicates that the precision and anti-jamming of the loading system are improved.
