在研究旋转弹舵机结构与控制原理的基础上，结合弹道修正引信的特点，设计一种适合修正引信的电动舵机。通过对舵机原理的研究，提出了相应的舵机控制方法。之后经仿真研究，结果表明所设计的无刷电机驱动的舵机，在交变载荷作用下，舵机能确保工作中与弹的相位对准、转速同步。关键词：弹道修正；舵机控制；仿真Abstract：Based on the structure and control theory of the spin missile actuator and considering the characteristic of the correction fuze, a electromechanical actuator is designed.A control method of the electromechanical actuator is discussed by the actuator work theoryresearched. Simulation results indicate that the designed electromechanical actuator, which isdriven by a brushless DC motor and is forced by the alternate loading, can ensure theaccuracy of phase compensation and rotation synchronization.Key words：trajectory correction；actuator control；simulation
