摘要:

随着导弹飞行速度的提高，弹体姿态稳定所需的操纵力矩加大，舵面气动加热效应加剧，舵面的尺寸和惯量势必增加。在电机、传动机构与控制算法确定的前提下，舵面惯量对机电舵系统具有何种影响，成为提高机电舵系统控制要求的关键问题。在搭建的电机—传动机构—负载的三质量模型基础上，从理论及仿真上进行了惯量负载对舵系统的影响分析，并在某机电舵系统上进行了试验验证，为研究大惯量负载机电舵系统提供了理论依据。

Abstract:

When increasing the missile flight speed, it needs more steering torque to maintain the stability of body attitude Following with that, the aerodynamic heating effect intensifies, so the inertial and size of the rudder must be increased to keep the balance of the attitude The inertial of the rudder has great effect on the EMA on the premise that the motor, driving mechanism and the load are selected, which becomes the key problem of improving EMA control requirement Based on the the motor-driving mechanism-load three-mass model, the paper analyses the effect that heavy inertial load has on the EMFAS in the aspect of theory and simulation , and has an experiment on tne system, which provides academic basis for electromechanical fin actuation system under heavy inertial load.
