结构主动抗振状态参数敏感度及准最优控制

Analysis of Sensitivity of State Parameters and Suboptimal Control in Structural Active Vibration Control

结构主动抗振中，因环境条件、测量手段等限制，不可能测得全部状态参数以满足全状态反馈意义上的最优控制．对状态反馈参数进行敏感度分析，以确定关键的状态反馈参数，实现准最优控制，可达到较好的控制效果．

In structural active vibration control, it is hard to get all the state parameters to satisfy the optimal controlwith all state feedback due to limitation of environmental conditions and measure methods. After analyzing the sensitivitg of the feedback state parameters individually, the key stateparameters can be found, and then the suboptimal con- trol can be realized, and a good control can he reached.
