摘　　要：介绍了一种基于开放式多轴运动控制卡PMAC和松下伺服电机同步检测数控系统.以IPC为系统上位机,以PMAC为系统控制核心以松下交流伺服系统为驱动.从理论上建立了伺服电机PID控制模型,并用S imu link仿真软件在KP=0.55,KI=1.8,KD=0.04情况下进行了仿真,0.05 s达到了控制要求.试验上用小蜜蜂数控切割机完成了两台交流伺服电机同步检测与控制,得到了同步运行的误差,结果表明基于PMAC的伺服电机同步控制系统相对偏差绝对平均值为2.919%,达到气割数控系统的技术和精度要求.A synchronous detection NC system is introduced based on an open multiaxial PMAC controller and Panasonie servo motor where IPC is used as host computer. PMAC as control system center, and Panasonic servo AC system is used as driving. The PID control model of the servo motor is built with Simulink software, and the simulation is carried out under the conditions of Kp = 0. 55,K1 = 1.8 and Ko = 0.04 with the result met the requirement of 0. 05 second. By using Honey Bee CNC cutting machine to complete synchronous detection and control of the two servo motors, the synchronous operation error is obtained. The result shows that the servo motor synchronous control system reaches the requirements of technology and precision of gas cutting NC system with the relation deviation absolute average of 2. 919%.
