基于压电叠层作动器的柔性自旋导弹振动控制

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.
