【Abstract】 A real-time adaptive feedback predictive control system excited by periodic disturbances and its application to structural vibration control are studied in this paper. 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.更多还原
