摘　　要：交流伺服系统的控制结构及其控制器性能直接影响整个系统的动态性能,基于PMSM的交流伺服系统内环电流环调节是高性能伺服系统构成的根本。文章在分析了交流伺服系统三环控制结构的基础上,建立了电流闭环控制的动态数学模型并进行等效简化,设计了电流环调节器及对系统性能进行校正,在MATLAB/SIMULINK环境进行了数控铣齿机床伺服系统电流环整定计算。结果表明电流环整定提高了系统的快速性和抑制电流环内部的干扰,系统性能显著提高。Controlling structures and properties of controller effect dynamic properties of all the system in AC servo system. Base on PM SM, regulating the current loop of AC servo system is the basic of high performance servo systems. Three loops controlling structure of AC servo system was analyzed by this paper. In this paper, dynamic mathematical model of closed current loop were established and simplified. The controller of current loop was designed. The system was corrected by the controller. In NC gear milling machine, tuning and calculation of the current loop was carried in M ATLAB/SIM ULINK. The result indicated that the tuning of current loop enhanced the rapidly of the system and inhibited the internal interference of the current loop. Properties of the system were enhanced.
