弹性体导弹主动减振组合控制器设计

将导弹弹体弹性变形引起的附加气动力引入导弹刚体运动方程和弹性振动方程,推导出弹性体导弹数学模型,在此基础上引入主动作动力,建立起适合进行主动减振设计的弹性体导弹状态空间模型.针对解耦的刚性子系统设计H∞控制器模拟刚体导弹控制器,针对弹性子系统设计LQR控制器,再考虑耦合项对弹性子系统进行控制器设计,得到主动减振组合控制器.仿真结果验证了所设计的组合控制器在保证弹体运动姿态控制的同时具有较好的减振效果.

Assembling Controller Design of Active Vibration Control of Elastic Missile

The elastic missile state space model is established by introducing additional aerodynamic force,caused by the elastic deformation of missile,to rigid body motion equation and elastic vibration equation.In order to design active vibration control,the active control force is introduced to the state space model.The H∞ controller is designed as rigid missile controller for decoupling rigid subsystem,and LQR controller for decoupling elastic subsystem.Then,the controller for coupling elastic subsystem is design...
