最小控制合成算法在结构振动控制中的应用
|
摘要
将模型参考自适应控制方法引入结构减震控制领域中,基于"最小控制合成算法(MCS)"的自适应控制理论,推导了建筑结构地震反应自适应控制的基本方程。提出了以地震能量降低模型为最优控制模型,设计并研究了该模型的自适应控制器。以地震能量降低模型的MCS自适应控制方法,对一个三自由度受控结构和天兴洲大桥MR磁流变阻尼器进行仿真分析。仿真结果表明:受控结构响应能够很好的跟踪参考模型响应,自适应控制器可以明显减小结构的地震响应。
The model reference adaptive control method is introduced into the field of structural control.The fundamental equation about adaptive control over the seismic response of the structure is derived from the adaptive control theory-the minimum control synthesis(MCS).On the basis of designing one reference model-the seismic energy reducing model,the adaptive controller is devised for each model.This method is used to analyze three degrees of freedom controlled structure and Tianxingzhou Bridge MR damper.The simulation results show that the controlled structural response can be a good reference model to track responses,and adaptive controllers can significantly reduce the structural seismic response.
