摘　　要：针对高速数控机床的应用需求越来越多,以交流永磁同步直线电动机为驱动元件的高速伺服系统是最为有效的解决途径。以数控机床直线交流伺服系统为研究对象,首先进行了主回路及配电的设计,然后对其中主要部件进行选型。然后针对核心部件永磁同步直线电机建立电流、速度、位置三闭环的PID控制模型,应用PID优化理论及模糊自适应理论,对PID参数进行整定优化,并用MATLAB/SIMULINK进行动态仿真、计算,仿真结果表明采用上述方法提高了数控机床交流伺服系统设计整定的效率和精度、改善了系统动态响应性能。Aiming at more and more applications demand for high-speed CNC machine tools,AC permanent magnet synchronous linear motor-driven system is the most effective solution.In order to study the linear AC servo system of CNC machine tools,the main circuit and power distribution are designed first,and then the main components selection.For the core components of permanent magnet synchronous linear motor current,speed,location of closed-loop PID control model,with the application of PID optimization theory and fuzzy adaptive theory,the PID parameter tuning optimization,and dynamic simulation is used to calculate and simulate with MATLAB/SIMULINK,and the results show that using the above method can improve the efficiency and accuracy of CNC machine tool servo system,and improve the performance of the system dynamic response.
