摘　　要：研究一种周期扰力作用下的自适应反馈预测实时控制方法 ,并将其应用到结构振动控制中。采用 RL S算法处理在线辨识问题 ,根据辨识结果直接进行反馈预测控制的设计。实时控制中 ,辨识和控制的计算都由高速数字信号处理器完成。此种方法 。A real-time adaptive feedback predictive control system excited by periodic disturbances and its application to structural vibration control are studied. The real-time system identification is realized by Recursive Least Square (RLS) method, then the control law is determined based on the identified results. In control system, system identification and control are calculated by a high speed digital signal processing unit. Exciting results are obtained when the presented control algorithm are applied to the structural vibration with periodic and pseudo-periodic disturbances.
