交流异步电机磁场定向控制探索

Research on Field Orientated Control (FOC) for Three Phase AC Induction Motor

将磁场定向控制(FOC)应用于交流异步电机调速系统,通过对磁场定向控制和数字实现空间矢量脉宽调制原理以及控制系统实例的分析,得出该控制方法不仅具有控制精度高,系统响应快等优点,而且数字实现方法简单。该方法不仅可以实现异步电机的变频调速控制,而且可以应用到高精度、快响应的伺服控制系统中。

This paper introduces the principle of Field Orientated Control （FOC） of three phase AC induction motor in detail, and a digital methodtO achieve Space Vector Pulse Width Modulation （SVPWM） also is introduced briefly. Both the theoretical and practical characteristics of this drive implementation allow the reader to quickly gain and understanding of the Field Orientated Control of an induction motor. As such, the reader might not only gain a reliable and highly effective induction drive, but also gain a short time to market solution.
