Abstract

This paper presents a comparative study of the most significant control methods (scalar control (V/F), indirect field oriented control (IFOC) and direct torque control (DTC)) for an induction motor fed by a Z-source inverter (ZSI) for automotive applications. The three control techniques are implemented using PWM voltage modulation. The comparison is based on various criteria including: the motor dynamic performance, the speed and torque ripples, the ac current harmonic content, the control algorithm implementation complexity, the ZSI performance and the overall system efficiency. The study is done by MATLAB simulation of a 15 kW induction motor fed by a high performance Z-source inverter. The simulation results indicates that, the IFOC seems to be the best control techniques suitable for controlling an induction motor fed by a ZSI for automotive applications. In addition, this paper proves that, all control methods used for the voltage source inverter (VSI) can be applied for the ZSI and gaining its advantages.

电动汽车z源逆变器感应电机不同控制技术的比较研究

本文对汽车用z源逆变器(ZSI)感应电机的几种最重要的控制方法(标量控制(V/F)、间接磁场定向控制(IFOC)和直接转矩控制(DTC))进行了比较研究。这三种控制技术是使用PWM电压调制实现的。比较的标准包括:电机动态性能、转速和转矩脉动、交流电流谐波含量、控制算法实现复杂度、ZSI性能和整体系统效率。通过MATLAB仿真，对采用高性能z源逆变器供电的15kw感应电机进行了研究。仿真结果表明，IFOC似乎是适用于汽车应用中ZSI馈电感应电机控制的最佳控制技术。此外，本文还证明了电压源逆变器(VSI)的所有控制方法都可以应用于ZSI，并获得其优势。
