Based on a duralumin flexible beam with piezoelectric films attached , distributed parameter modal described by partial difference equations is builded , and then turned into a set of two order systems with the method of modal analyse . state feedback control and independent modal control is investigated . and simulation of the closed - loop system with thest two methods is performed in matlab 并用模態分析的方法,將系統的偏微分方程模型轉化成了模態模型;研究了狀態反饋和獨立模態方法;進一步完善了軟件界面以及軟件功能;在實際系統中,應用狀態反饋算法,有效抑制了懸臂梁在受到外界瞬時脈沖擾動和激振引起的一階、二階模態振動。
