Abstract :
As the accuracy of the control channel model directly affects the stability and the convergence of the active vibration controller for smart flexible structures, offline identification of the control channel model is inappropriate for a vibration system whose characteristic and parameter is time-varying. To solve the problem of the control channel model identification, an active vibration control algorithm based on online control channel identification is proposed in this paper. Adopting a noise signal as the input identification signal, the FIR filter structure as the system model structure, and FxLMS algorithm as the control algorithm, the detailed derivation of the algorithm is presented. To test and verify the feasibility and priority of the proposed algorithm, simulation analysis is done by Matlab, while the actual experiment is done on the experimental active vibration control platform. The experiment results show that the proposed algorithm is feasible with good control performance and rapid convergence.
