The multiresolution method is extended and applied to random vibration control system, thus a multiresolution random vibration control algorithm is created, which provides a satisfied solution to the poor control precision problem at low frequency that was pointed out and remained unsettled for many years. the control algorithm has been successfully implemented on dactron ' s shaker control system, showing great improvement in low frequency control precision, with a little more computation resource consumed. high resolution octave analysis is another successful application of multiresolution spectrum estimation theory
在多抽樣率信號處理理論和多分辨譜估計理論的基礎上，本文進而將多解析度思想推廣到隨機振動控制理論中，提出了多分辨隨機振動控制演算法，解決了振動控制界多年來懸而未決的低頻控制精度問題，並在dactron公司laser ~ （ tm ）和comet ~ （ tm ）等多種振動控制產品中得到了成功的應用，在計算量增加不大的前提下取得了令人滿意的控制效果。 -
It is a well - compromised solution to both the computation resource problem and measure time problem. compared to the integrate average method, which is found widely used in octave analysis, this algorithm saves much computation. dsp - based real time hardware design is also studied in this thesis
