针对频率周期振荡的振动系统讨论自适应控制问题,在频率跟踪的基础上对频率变化的振动响应进行控 制,给出相应的估计、滤波与控制方法。首先在子空间辨识原理的基础上,通过测量信号自相关序列的递推运算获得信号 频率 然后根据估计频率实时调整带通滤波器的中心频率,使其跟踪信号频率,实现信号分量的跟踪滤波 最后在LMS方 法的基础上构造对信号分量进行控制的自适应控制器。(The adaptive vibration control of systems excited by forces of periodically varying frequencieswas dis- cussed. The presented adaptive controlwas realized on the basis of tracking of time-varying frequencies and amethod for online frequency estimation, filtering and controlwas proposed. Based on the principle of subspace identification, the time-varying frequencieswere estimated from the recursively computed autocorrelation ofmeasured signals. )
