振动系统在不可测干扰作用下的主动控制研究

Study of Active Control for Vibration Systems with Unmeasurable Disturbances

基于模态控制理论，利用优化特征值配置和稳定性理论等技术，提出阻尼线性振动系统在不可测外扰作用下主动控制的一种设计方法。实验结果表明：对于低频振动系统，采用该方法设计控制系统可有效地降低系统的振幅，取得满意的控制效果。

Based on the modal control theory,a design method of active controller for damped vibration systems subjected to external unmeasurable disturbances is developed in this paper.The parameter design of the control system is based on the combined applications of optimizing eigenvalue asignment and stability theory.The experimental results show that for low frequency vibration systems,good control effect can be achieved using the design method presented in this paper.
