Abstract: This work focuses on investigation and evaluation of the performance of a permanent magnet brushless dc motor (BLDCM) drive, controlled by PID or fuzzy logic control techniques. The mathematical models of brushless DC motor with sinusoidal back EMF supplied from three-phase inverter operating at 180o conduction mode, and that with trapezoidal back EMF supplied from three-phase inverter operating at 120o conduction mode are given. In the simulation part the mathematical models are transferred to simulink models for PID and fuzzy logic control techniques. The gate driving simulink models for each control technique and for each mode of operation are designed and implemented. The system speed responses under the influence of load changes and set speed changes are presented. The three-phase currents, voltages, and electrical torque waveforms are presented. An experimental setup was constructed and tested. It consists of BLDCM, inverter, DC generator with variable resistive load and two personal computers .The load is automatically changed during operation by switching on and off relay contacts controlled by microprocessor. The fuzzy or PID control algorithms are implemented in one of the used personal computers while the other computer is used for data logging via a data acquisition card. In this study the system performance with PID controller and fuzzy controller is investigated and tested to achieve speed control under different loads and set speeds.
