摘　　要：运用非线性控制理论设计了一种电动舵机系统的非线性PID控制器.主要用于提高导弹在飞行过程中电动舵机系统在存在外部干扰时的性能.对电动舵机进行了分类,分别建立了其对应的数学模型并进行了仿真.仿真结果表明,与传统的PID控制相比,该控制算法具有较好的动态性能,且在外部扰动情况下具有较强的鲁棒性.Based on the nonlinear control theory,a nonlinear PID controller for an electromechanical actuator system is designed.It is mainly used to improve the performance of system during the missile flight,which can bring disturbances.All kinds of electromechanical actuator are classified and each model is established and simulated.The simulation results show that this scheme has better dynamic properties and robustness than that of traditional PID control in disturbed condition.
