摘　　要：与转差闭环控制相比，矢量控制可使异步电机获得更好的动态响应，显著提高机车性能。文章针对这一特点提出了电压解耦型矢量控制方案和相应的脉宽调制规律，并设计了基于数字信号处理器和单片机的双微机控制系统，以实验结果验证了该控制方案的可行性。Asynchronous motor can get better dynamic response with vector coned rather than slip close-loop control, and theperformance of electric locomotive will be improved remarkably. A voltage--decoupling vector control scheme and corresponding PWM strategy suitable to above mentions characteristic of electric locomotive is proposed in this article, the Digital Signal Proces- sor (DSP) and micro-comtroller based dual--processor vector control system is also designed. The feasibility of control scheme is verified by experimental results.
