A Double Channel High Precision Servo System Based on TMS320F2812

设计了一套双通道高精度伺服系统。系统以TMS320F2812为控制核心,采用旋转变压器作为位置检测单元,伺服电机为无槽无刷直流电动机,运用电压空间矢量调制技术实现控制算法。实验结果表明,系统运行平稳,具有较好的动态性能,达到了双通道高精度控制的目的。

A high precision double channel servo system was designed in this paper. The system was set up based on TMS320F2812, and a resolver was used to test the rotor position of the slotless brushless DC motors precisely for each chan- nel. Space vector pulse width modulation was realized to control the brushless DC motor. Test results proved that the system had excellent performance in high precision while two motors worked together.
