摘要
在全数字交流伺服系统中用数字信号处理器(DSP)进行电流控制。根据矢量控制原理在电压型逆变器中实现电流跟踪,分析了电流控制和双边不对称规则采样技术的原理和实现方法。实验结果表明本电流控制器具有良好的控制性能。
A full-digital AC servo system is presented. It complements current control by using digital signal processor (DSP). The motor currents are forced to follow reference currents generated by vector control strategy on voltage inverter. The scheme of current control and asymmetric double-edge sampling technique is described. Experiment result shows that this current controller has good control performance.
