摘要
实际生产中各环节的微小变化都将需要伺服系统控制参数的及时调整以保证系统运行的平稳、准确,为便于研究控制参数调整对系统的影响,在分析了交流永磁伺服进给系统一般性组成的基础上,对系统中的机械传动装置、永磁同步电动机及检测反馈器件分别建立了数学模型,并针对市售永磁同步电动机的非开放性进行了基于实测数据的速度控制模型参数辨识,所得到的电动机参数经过验证证明了该辨识方法的可行性。搭建了交流永磁伺服进给系统的整体仿真模型,并进行了仿真实验,仿真实验结果与实测结果吻合,证明了该模型的正确性。
To guarantee the smooth and precise operation of an AC servo system,the controller＇s parameter should be adjusted in time,while some tiny change happened in the system. For the purpose of facilitating the study on howthe adjustion affect the whole system,a model of permanent magnet AC servo feeding system is established in this paper. On the basis of analysis of an AC servo feeding system ＇s normal structure,the model of each component,including mechanical transmission,PMSMand detection feedback device,is established respectively. As the incomplete open of the PMSM,an identification method,based on data of actual measurement,for the velocity control loop＇s parameter is proposed. Comparing the simulation and actual data,the identification method is proved to be proper. The entire simulation model of the AC Servo feeding system is established. The simulation results well match the actual situation,and verify the validity of the model established in this paper.
