dc.description.abstractThis thesis presents simulation and hardware implementation of a 3-phase PM brushless DC (BLDC) motor drive using 120-degree, six-step current commutation control technique. The microcontroller used is PIC16F877 which functions to perform current commutation sequence, rotating direction control, speed control and reading Hall sensor signals. This microcontroller is a common and low-cost 40-pin MCU. The sensored type of controlling technique has been chosen in order to make this design suitable for both low speed and high speed applications plus control simplicity. For this controlling technique, the rotor position detection is crucial to perform electronic commutation of the motor drive so that the right sequence of current flowing in the three-phase motor windings can be made. Before the hardware is constructed, the BLDC motor model was simulated by using two software: Matlab Simulink and Proteus VSM software. The Matlab Simulink provides simulation based on mathematical equations. From here, important parameters of the motor such as phase current, phase voltage, back-EMF and speed can be monitored. The second simulation was performed by using Proteus VSM software. This software provides simulation based on real electronic components behavior that will be used in hardware development stage. Through this simulation, expected results can be monitored and analyzed virtually. The most important characteristic of this software is its ability to directly program the MCU as intended. To complete this research, the prototype for the BLDC motor drive has been developed following the circuit simulated in Proteus VSM software. From test and measurement conducted, it is found that the experimental results are in good agreement with the simulation results.en_US
