摘　　要：以某回转平台为研究对象,采用虚拟样机技术与控制理论,对其机电传动系统的控制方法进行了研究。基于赫兹弹性接触理论,在RecurDyn/Gear中建立了回转平台的虚拟样机模型,在Colink中设计了具有前馈环节的位置、速度和电流三环电机控制系统,在此基础上搭建了回转平台机械与控制联合仿真模型,进行了典型输入信号的响应分析。仿真结果表明,该控制方法具有有效的工程应用性,传动系统位置控制能够满足工程控制目标,为其他机电传动控制系统的设计与分析提供了参考。A rotary platform is studied. The control method of its electromechanical transmission system is stud- ied by using virtual prototype technology and control theory. Virtual prototype model of rotary platform is established in RecurDyn/Gear based on the Hertz elastic contact theory. A feed - forward link and three - ring control system which are position, speed and current control link are designed in Colink. And then, the mechanical and control simulation model is set up. The response of the typical position command signal is analyzed. The simulation results show that the control method has effective engineering application, and the method can satisfy the objective of engineering control and a reference for the design and analysis of other electromechanical transmission control system is provided.
