Abstract—In this paper, an eleven-phase permanent magnet brushless DC motor fed by an eleven-leg two-level inverter is modeled and simulated. In order to produce trapezoidal back electromotive force waveforms by permanent magnet rotor, the motor has concentrated stator windings. The motor speed is controlled by Mamdani-type fuzzy incremental controller. The hysteresis modulation is used for switching operation. The simulation is carried out by Matlab/Simulink.
Index Terms—Fuzzy incremental controller, hysteresis band, permanent magnet brushless DC motor, voltage source inverter.
