Modelling and Comparison PID Fuzzy Controllers for Six-phase Drive

The paper presents a MATLAB Simulink model of a symmetrical six-phase drive controlled by the six-phase frequency converter with PID fuzzy controllers. Six-phase motor model is elaborated in a rotating
$\boldsymbol{d-q}$
reference frame. Two types of fuzzy controllers based on 25 and 49 linguistic rules together with the control system are modelled and simulation results are compared. Both elaborated systems distinguish with high-quality speed response specifications and indicate the robustness of the modelled system to disturbance and great accuracy following the reference input.
