摘　　要：针对柔性自旋导弹弹性振动问题,提出将压电叠层作动器应用于导弹弹性振动控制方法。将导弹简化为非均匀自由-自由Timoshenko梁模型,考虑陀螺效应和推力作用,将压电叠层作动器应用于导弹弹性振动,基于有限元方法建立含有压电叠层作动器的柔性自旋导弹动力学模型,同时设计模糊滑模控制器,对质量偏心引起的不平衡响应进行数值仿真,通过与不同控制方法进行对比,验证该方法的有效性。Aiming at the problem of elastic vibration of flexible spinning missile,a method of applying piezoelectric stack actuator to the control of elastic vibration is proposed.The flexible spinning missile is simplified to a non-uniform free-free Timoshenko beam model,considering the gyro effect and thrust,the piezoelectric stack actuator is applied to the elastic vibration of the missile,and the dynamic model of flexible spinning missile with piezoelectric stack actuator is established based on the finite element method.The fuzzy sliding mode controller is designed.Different control methods are compared to verify the effectiveness of the method.
