Speed Control of an Eleven-Phase Brushless DC Motor
Keywords:
Fuzzy incremental controller, hysteresis band, permanent magnet brushless DC motor, voltage source inverter.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.
