摘要

基于市场机制控制策略（Market-based control, MBC）是一种多目标优化算法。为检验MBC在实际结构振动控制中的控制效果，本文进行了基于MBC的模型结构振动控制实验研究。实验选用压电陶瓷片作为驱动单元和传感单元，在dSpace系统平台下，结合Matlab/Simulink工作环境，完成了MBC控制算法在实际模型振动控制中的应用。实验过程中分别对自由振动（无控）状态下和MBC控制状态下的模型结构进行了振动反应测试，获得了模型结构在输入同一正弦激励后自由振动与MBC控制状态下的结构振动响应，并对实验结果进行了对比分析。实验结果表明，MBC算法应用于实际结构中具有较好的减振控制效果

Abstract

market-based control method (MBC) is a kind of multi-objective optimization algorithm. Vibration control model was studied in this paper in order to test the effectiveness of the MBC method in actual structures. Piezoelectric was used as driving and sensor unit and MBC method applying in vibration control of the practical model was completed in dSpace system coupled with Matlab/Simulink working environment. Responses of the structure model were tested between free vibration state and MBC condition, and experimental result was analyzed in those two different conditions after inputting a same sine excitation in the processing of the test. It shows that MBC method has better efficient of vibration reduction of the structure.
