【摘要】 导出了三轴液压振动系统的线性化模型。基于此模型,分析了由于被试件具有高度和偏心所造成的瞬态力耦合。为消除这种耦合作用,设计了一种反馈解耦控制器。仿真结果表明该控制器能够有效消除系统存在的瞬态力耦合。更多还原

【Abstract】 A method of deriving linear model of 3-dimention hydraulic shaking system was presented.Based on the linear model,coupling vibrations of shaking system due to height,eccentricity of the specimen were analyzed and then a feedback decoupling controller was designed to eliminate the coupling vibrations.A simulation demonstrates the validity of the approach.更多还原
