摘要
给出了用于转子系统强迫振动主动控制的自适应控制方案，它主要由可控径向轴承和自校正控制器两部分组成。可控轴承为系统的执行元件，自校正算法则由多步递推预报器和控制器组成，通过在线测量转子系统输入输出值，调整油腔压力而使强迫振动振幅减小。仿真计算表明自适应控制适用于转子系统强迫振动控制，转子不平衡引起的振动幅值可有效地减小。
A multivariable self tuning adaptive control for forced vibration of rotor systems, which basically consists of an active journal bearing and a self tuning controller, was presented in this paper. The active journal bearing was used for a control element. The control algorithm is based on the multi step parameter predictor and the self tuning controller. The scheme minimizes the forced vibration of a rotor system by measureing the input/output of systems. The computer simulation showed that the adaptive control algorithm is suitable for the forced vibration control of the rotor system and the amplitude of the vibration due to rotor unbalance can be reduced effectively.
