Abstract
The paper presents MATLAB Simulink model of symmetrical six-phase motor drive controlled by the six- phase frequency converter and analyses its performance at indirect rotor flux field oriented control mode. The new control blocks not entering the Simulink library, were elaborated for control six-phase motor. Simulink model of the motor was elaborated with the actual parameters of real six-phase motor having displacement of phase windings sets 60 electrical degrees. The model of the field oriented control for six-phase motor with Fuzzy controllers is elaborated and simulation results are presented and analysed. Step response of controlled system has shorter settling time, less torque oscillations, system does not lose its benefits at small reference speed. The response of followup system to ramp input, sine wave input, trapezoidal shape input, were simulated and analysed.
