摘　　要：基于MATLAB的模糊逻辑工具箱图形界面(GUI)工具,对数控车床永磁电动机模糊控制系统进行综合与分析。模糊控制器的输入语言变量选择为速度误差以及误差的积分,输出语言变量选择为电流的给定量,这样既能实现模糊控制不依赖被控对象模型,又能发挥比例积分控制规律稳态无误差的优点。采用模糊逻辑工具箱图形界面工具进行系统的综合与分析,可以方便地修改语言变量的论域、隶属度函数和模糊控制规则,设计过程简单清晰。仿真结果表明,采用该方法设计的模糊控制系统鲁棒性强,满足高速磨床永磁电动机系统对给定速度的准确跟踪和对扰动的抑制。This paper present a synthesizing and analyzing method on fuzzy control of permanent magnet synchronous motor control system for CAK6163Di NC lathe based on graphical user interface （GUI） tools provided by MATLAB fuzzy logic toolbox The speed error and error integral are selected as input variables of controller. The output of controller is regard as output variables of controller. Fuzzy control strategy do not depend on mathematical model. At the same time, the merit of PI controller is achieved in a fuzzy control system. In addition, when GUI is used for synthesizing and analyzing, one of the primary goals of the fuzzy logic toolbox is to have an open and easily modified fuzzy inference system structure, such as the range of variables, membership function and fuzzy rules. Thus, the fuzzy logic toolbox is designed to give you as much freedom as possible. The results of computer simulation indicate that the system robustness is strikingiy improved, and the fuzzy controllers can guarantee a good disturbance restraint as well as the tracks of input signal.
