基于DSP的双轴交流伺服运动控制系统

Double Servo and Movement Control System Based on DSP

针对传统伺服电机的运动控制方式的不足,以工业缝纫机系统为研究对象,提出一种基于DSP的双轴交流伺服运动控制系统。该系统将运动控制与伺服驱动合二为一,用于工业缝纫机控制系统作为从机控制部分。该运动控制系统可控制4个步进电机(轴1,轴1,轴3,轴4),2个交流伺服主轴电机(轴A,轴B),具有16个光电隔离的输入、输出,5个光电隔离的电磁铁输出、2个PWM调节的LED灯驱动输出。试验表明,该系统工作可靠,实时性高,成本低,安装使用方便。

Aimed at the disadvantage of the method of traditional servo motors’ motion and control,this article takes the industry sewing machine system as the object of study,and proposes one kind of two axle AC servo motion and control system based on the DSP.This system combines the motion control and the servo,and is used in the industry sewing machine to serve for the control section of subordinate machine.This motion control system can control 4 stepper motors（axes 1,axes 2,axes 3,axes 4） and two main axle motors of AC servo（axes A,axes B）,simultaneity it has 16 photoelectric isolation inputs and outputs,5 photoelectric isolation electro-magnet outputs,and 2 adjustable PWM led lamps used to driver output.This experiment indicates that the system is reliable,real-time,low cost,convenient installation and use.
