摘要
根据电动舵机工作原理,推导了电动舵机的数学模型,电动舵机控制中采用滑模变结构控制。仿真结果表明:与传统比例积分微分(PID)控制相比,基于滑模变结构控制的电动舵机的快速性、抗负载能力、抗干扰和鲁棒性等有较大改善。
According to the principle and mathematical model of electromechanical actuator, sliding mode variable structure controller were applied to the control of electromechanical actuator in this paper. And the simulation results showed that the performance of electromechanical actuator based-on sliding mode variable structure would improve effectively in response speed, anti-disturbance, anti-jamming and robustness which compared with traditional PID.
