Study of AC Asynchronous Motor Voltage-decoupled Vector Control System Based on DSP

基于对交流异步电机电压解耦矢量控制原理的研究,提出了一种用DSP芯片实现交流异步电机矢量控制系统的设计方案,并在PWM变频器上进行了试验。结果表明,采用基于DSP的电压解耦矢量控制系统不但系统简单可靠、性能好而且易于实现复杂的控制策略。

Based on the voltage decoupling principle of vector control for the ac asynchronous motor, a design of vector control system of the ac asynchronous motor, which was executed by DSP chip, was put forward. The construction of hardware and software for this vector control system was confirmed. And this system was experimented on a PWM frequency convertor. The results showed this vector control system of the ac asynchronous motor not only had the advantages of simple construction and reliable operation but ability to realize the complex control strategies.
