    • 本文分別以數值模擬與實驗進行振動控制；主要目的是藉由黏貼於複合材料樑上、下表面之壓電感測器和壓電致動器配合不同之控制律，同步感測出擾動並加以抑制其振動；在數值模擬部份利用MATLAB/Simulink建立模擬平台，而在實驗部分以LabVIEW作為整合實驗所需軟體與硬體之工作平台。在模擬與實驗平台上設計撰寫符合LQG/LTR與PID二種控制律之控制器進行系統之振動控制；最後分別就模擬與實驗之結果討論其中之異同。

    The primary intention is that we proceed the vibration suppression of composite beams with numeric simulation and the experiment. The main purpose is to measure the perturbation and suppress vibration simultaneously by the piezoelectric detecting and actuating device adhered on the surface of the composite beam. This study is divided into two sections. In simulation, we exploit MATLAB/Simulink as a working platform; in experiment, we utilize LabVIEW as a platform integrating the software and hardware. Then we code a program conforming to the LQG/LTR and PID control theorems in the platforms to process vibration suppression of the system. At last, the similarities and differences of the results obtained from numeric simulation and the experiment will be further investigated.
