Active Control Based on Prediction of Structural Vibration Feedback

Faced with the problem of time-delay in the structural active control, the active control based on the output vector prediction in the structural vibration is proposed. Also, the thesis devises a plan of forecast active control, where the gray model GM (1, 1) is used as the prediction model and the Matlab program is applied to the Computer Simulation Analysis. Adopting the plan in the aseismatic control of a 5-floor building and comparing the computation results with the control effect acquired from the references, numerical simulation results show that the gray forecast active control can lessen the time-delay effects on the structural vibration control which is superior to that in the references.
