摘　　要：以音圈电机作为作动器,采用"Cubic"构型的Stewart平台设计主动隔振系统。这种Stewart平台的各杆之间线性无关,耦合作用可以忽略不计,采用六路相同的控制方法对Stewart主动隔振平台进行分散控制,简化了控制系统,提高了系统的可靠性。通过分析设计了双层结构的单主动杆形式,并对其采用"前馈—反馈"的复合控制方法,并用六个单主动杆构成Stewart平台。对整个系统进行Adams/View和Matlab/Simulink的联合仿真,分析仿真结果可以看到所设计的主动控制系统具有良好的隔振效果。Stewart of Cubic form was used to design active vibration isolation platform,using voice coil motor(VCM)as actuators.Bars in this form of the Stewart platform was linearly independent of each other,so coupling effects can also be ignored.Six identical decentralized control strategy were used to control the Stewart platform,thus simplified and improved the reliability of the control system.Double-layer single-active bar was designed,using compound control method of feedforward—feedback.Adams/View and Matlab/Simulink co-simulation results show that the active control system has excellent vibration isolation effects.
