【摘要】 针对在前馈/反馈混合控制中提高控制通道阻尼的问题,基于自适应滤波理论,提出适用于单输入单输出(SISO)和多输入多输出(MIMO)控制通道的时域自适应反馈主动阻尼设计方法。研究了自适应过程的理想期望信号的构造、SISO情况下闭环控制通道与反馈控制器同时进行自适应设计以及MIMO控制通道阻尼问题的简化与设计方法的拓展等问题;同时,基于某主动隔振试验平台的实测结果,对所有研究内容进行SIMULINK模型仿真。时域自适应反馈主动阻尼设计是高效的主动阻尼设计方法,并且为小阻尼动态系统的增阻设计提供了统一的方法框架。更多还原

【Abstract】 An active damping method with time-domain adaptive feedback controller is proposed to improve damping ratios of the control path in feedforward/feedback hybrid control systems. Topics for constructing the ideal expected signals, extracting the estimations of both closed loop and feedback controller simultaneously for single-input single-output (SISO) systems as well as simplifying the damping model and expanding the control strategy for multiple-input multiple-output (MIMO) systems are studied. Based on the measured transfer matrices of a real test for active isolation, simulations are conducted for all subjects mentioned above with MATLAB/SIMULINK. It is concluded that the method provides an uniform framework for highly efficient damping engineering of the dynamical systems with light damping.更多还原
