Synthesis controller design for the active mass driver system in the presence of the uncertainty

针对AMD(active m ass damper)Benchm ark问题,将μ综合控制理论引入到结构控制领域.详细阐述了μ设计权函数的选取方法,建立了AMD系统的综合设计模型;根据μ理论设计了控制器,并通过平衡截断法对控制器进行降阶得到三阶控制器;最后对系统的鲁棒稳定性和鲁棒性能进行了分析,仿真结果证明了μ控制器的有效性.

Focusing on the AMD benchmark problem, introduced μ synthesis control theory into structural control field. Method of selecting weighting functions for μ synthesis is described and system model of the AMD is formed. According to μ synthesis technique, controller is designed and a third order controller is achieved by balanced truncation procedure. Finally robust stability and robust performance of the AMD system is analyzed. The simulation results show that the μ synthesis controller is effective.
