一种鲁棒自适应主动振动控制方法

针对一类在有界输入和输出扰动情况下满足正实条件的主动振动控制的鲁棒自适应控制问题，提出一种鲁棒自适应主动振动控制系统，相对于传统的模太控制方法而言、此方法根据可直接测量的输出量构成控制律，因而不需要进行模太估计。基于有限维状态空间模型得到的鲁棒自适应控制律不存在由于模态截断引起的溢出问题。

A Method of Robust Adaptive Active Vibration Control

For a class of active vibration control systems with positive realness character and bounded input/output disturbances, this paper presents a method of robust adaptive active vibration control. In this method, the design of robust adaptive law is besed on finite dimension state space model and system output feedback. In comparison with conventional me thods of mode control, the method proposed in this paper avoids mode estimate and mode spillover. For a simple supposed beam, the simulation study of vibration control was carried out. The results show that the presented method is good of robustness and also good of suppressing vibration.
