Fuzzy logic control of In-Wheel permanent magnet brushless DC motors

In this study, the control of in-wheel permanent magnet brushless DC motor has been implemented using fuzzy logic controller. An inverter has been designed to drive the motor. The inverter circuit is controlled by fuzzy logic controller. The position of the rotor and the speed value is obtained from a magnetic sensor placed inside of the motor. According to the position of the rotor which phase of the motor is to be commutated is defined. The information of the error occurred in speed and the change in error is used as the input of the fuzzy logic controller. The speed of the motor can be adjusted to desired reference value by using implemented fuzzy logic controlled circuit. In the test setup prepared, the performances of PID (Proportional-Integral-Derivative) and fuzzy logic controllers has been compared by measuring the current, the voltage and the power of the motor.
