本文的主要目的是利用标量控制技术对感应电机的转速进行控制。感应电动机（IM）由于其较差的动态响应相比，直流电动机驱动。电压源逆变器（VSI）可以通过优化选择逆变器开关矢量来直接控制定子磁链和电磁转矩。采用标量控制技术（V/F），由于控制算法实现简单，加上闭环滑移补偿，响应更好、更准确。本文对空间矢量脉宽调制（SVPWM）下采用V/F方法的IM驱动器进行建模，更好地理解V/F方法及其难点。采用三电平逆变器，转速和转矩波动减小。然后使用电压矢量调制器实现参考电压矢量。基于实例给出了广泛的仿真结果。
The main objective of the paper is to control the speed of an induction machine with scalar control technique. Induction motor (IM) because of its poor dynamic response in comparison to the DC motor drives. A Voltage Source Inverter (VSI), it is possible to control directly the stator flux linkage and the electromagnetic torque by the optimum selection of inverter switching vectors. The scalar control technique (V/F) is used because of simplicity of control algorithm implementation and the response is better and accurate with closed loop slip compensation the modelling of an IM drive employing V/F method with application of Space Vector Pulse Width Modulation (SVPWM) is performed in this article, it is better to understand the V/F method and its difficulties. By using 3-level inverter, ripples in speed and torque will reduce. The reference voltage vector is then realized using a voltage vector modulator. The extensive simulation results are presented based on case studies.
