Experiment and Research on New Space Vector Pulse Width Modulation in Direct Torque Control of Induction motor

以异步电动机为控制对象,分析以一种新的空间矢量脉宽调制实现直接转矩控制的方法,即通过用相邻向量取代零向量来完成新的空间矢量算法。建立以DSP和IPM为控制核心的数字运动控制系统。实验结果表明系统在保留了传统SVM-DTC算法的优点的情况下运行良好。

Making induction motor as a control object to analyze a new space vector pulse width modulation algorithm which used adjacent voltage vector to replace zero voltage vector to realize direct torque control. Adopting to DSP and IPM to design control system to validate the algorithm. The experimental results were illustrated to show a good performance which had kept advantages of conventional SVM-DTC.
