Abstract
In this paper, a high-performance indirect field-oriented controlled dual Induction Motor (IM) drive fed by a single inverter using type-2 fuzzy logic control will be presented. At first, the mathematical model of the IM is implemented in the d-q reference frame. Then, the speed control of the Dual Induction Motor (DIM) operating in parallel configuration with Indirect Field Oriented Control (IFOC) using PI and type-2 Fuzzy Logic Controller (T2-FLC) will be presented. For the control of this system, a DC supply and a Space Vector Pulse Width Modulation (SVPWM) voltage source inverter are introduced with constant switching frequency. Also, the performance of T2-FLC, which is based on the IFOC, is tested and compared to those achieved using the PI controller. The simulation results demonstrate that the T2-FLC is more robust, efficient, and has superior dynamic performance for traction system applications.

This study is based in general on speed control of two induction motors connected in parallel associated to a single Space Vector Pulse Width Modulation (SVPWM) inverter with constant switching frequency, which uses Indirect Field Oriented Control (IFOC) as control technique
Summary
Industrial efforts are focusing on reducing weight and volume and on minimizing costs while guaranteeing high operating performance of the systems. A multi-machine drive system powered by a single inverter presents a desirable solution. These systems are used in several applications such as paper and steel rolling mills [1,2,3], conveyor systems [4], and electric propulsion systems such as electric traction, ship propulsion and electric vehicles [5,6,7]. Two induction machines connected in parallel powered by a single inverter as presented in Figure 1 [21] were considered. The speed control of the dual identical induction motor drive connected in parallel to a SVPWM inverter supply using T2-FLC is investigated in this paper.
