Abstract

This project presents the implementation of Torque Hysteresis Controller of BLDC Motor (BLDC) drive using a dSPACE 1104. BLDC motor is well-known and has been widely used in the industrial area due to its high speed and power density capabilities. Electronic commutation is by far more favourable compared to the conventional method, which uses brushes and commutators, that wear and tear by time. However, a precise controller is required in order to control the switches prior to commutation process. Over the past years, Torque Hysteresis Controller (THC) method for induction motor drives received lots of attention from researchers, and motor drive industries. THC of BLDC combines a simple control method and a demanding motor to complete a better drives system. THC method is known to have a simple structure without having complex calculations thus offers a fast response and a good dynamic performance. The previous work which is the Voltage Controlled of BLDC motor contributes a very high current during the start-up. A mathematical modeling which is created using Matlab simulation on the motor drive for Brushless DC Motor is presented along with a complete model of the THC system for BLDC motor using Simulink Block. The model is described briefly to give a better understanding on the whole system. Finally, the simulation and are shown to validate the performance of THC of BLDC motor with improvements of the problem highlighted
