In this paper, a parallel configuration is proposed for two quasi six-phase induction motors (QIMs) to feed them from a single six-phase voltage source inverter (VSI). A direct torque control (DTC) based on input-output feedback linearization (IOFL) combined with sliding mode (SM) control is used for each QIM in stationary reference frame. In addition, an adaptive scheme is employed to solve the motor resistances mismatching problem. The effectiveness and capability of the proposed method are shown by practical results obtained for two QIMs in series/parallel connections supplied from a single VSI. The decoupling control of QIMs and the feasibility of their torque and flux control are investigated. Moreover, a complete comparison between series and parallel connections of two QIMs is given.
本文提出了一种针对两台准六相感应电动机（QIM）的并联配置，以便由单个六相电压源逆变器（VSI）对它们进行供电。在静止参考系中，基于输入输出反馈线性化（IOFL）并结合滑模（SM）控制的直接转矩控制（DTC）用于每台QIM。此外，采用了一种自适应方案来解决电动机电阻不匹配问题。由单个VSI供电的两台QIM串联/并联连接所获得的实际结果表明了所提方法的有效性和能力。研究了QIM的解耦控制及其转矩和磁链控制的可行性。此外，还对两台QIM的串联和并联连接进行了全面比较。
