摘要
基于欧拉-自由梁模型理论得出弹性体导弹横向振动模型,用模态分析方法对模型进行求解。结合弹性导弹的刚体运动方程,得到包括横向振动和刚体运动的增广模型,对该模型进行鲁棒控制器设计,仿真结果表明,所设计的鲁棒控制器能够在保证弹体运动姿态控制的同时抑制横向振动。
By using Euler-Bemoulli theory, the transverse vibration model of flexible missiles is obtained. Modal analysis method is used for calculation of the model. Based on rigid-body kinematic equation of the flexible missile, the augmented model is obtained, which involves the transverse vibration and rigid motion equation, robust controller is designed. Simulation showed that this controller can not only guarantee the motion attitude control, but also restrain the transverse vibration of the missile.
