INSTANTANEOUS OPTIMAL CONTROL OF STRUCTURES BY USE OF WAVELET DECOMPOSITION

Abstract

This paper shows the method of instantaneous optimal control algorithm by using time-frequency domain data derived from real-time wavelet decomposition for seismic wave. To improve the precision of real-time wavelet decomposition, the method using time series prediction model is proposed and its effect is examined. Furthermore, proposed method is applied to feedforward control and its control efficiency is examined by simulation analysis in one degree of freedom system having one control system.
