Abstract

This paper, focuses on a low-cost speed control system using a fuzzy logic controller for a brushless DC motor. In digital control of a brushless DC motor, the control accuracy is of a high level, and it has a fast response time. We used a Hall IC signal for the permanent magnet rotor position and for the speed feedback signals, and also for a microcontroller of 8-bit type (80CL580); furthermore, we designed the fuzzy logic controller and implemented the speed control system of the brushless DC motor. To acquire an accurate fuzzy logic control algorithm, a simulation with the MATLAB program has been made, while the performance of the system, found by an experiment for a unit step response, was also verified
