Abstract

Due to its advantages such as high power density and low torque ripple, the multi-phase induction motors are preferred in high power industrial applications requiring wind turbines, in marine propulsion systems, and particularly in electric vehicles. Control of n-phase induction motor drive systems with nonlinear structure is performed scalar or vectorially. The scalar control technique, also called Volt/Hertz (V/f), has a simple mathematical model. For low-performance industrial applications, its applicability is easy and its cost is low. In terms of the microprocessor, it requires less operational load density. It is resistant against motor parameter changes. In this study, the open-loop speed control of a 6-phase induction motor with asymmetric winding structure was performed using the V/f control technique. The mathematical model of the 6-phase induction motor and the power circuit model of the 6-phase inverter were created in MATLAB/Simulink environment. Using the space vector pulse width modulation (SVPWM) technique, the stator voltage and stator frequency were controlled. In reference speed and load changes, transient and steady state performance analysis of the drive system was carried out. The obtained simulation results showed that the 6-phase induction motor could be successfully controlled by the V/f control technique.
