Abstract

This project is about the implementation of Torque Hysteresis Controller of Brush less Direct Current (BLDC) Motor. BLOC 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 favorable 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 BLOC combines a simple control method and a demanded from BLDC motor to complete a better performance. 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 startup. Furthermore, the conventional implementation gives large ripple with uncontrollable in the restricted bandwidth of hysteresis. A mathematical modeling which is created using Matlab/Simulik simulation on the motor drive for Brushless DC Motor is presented along with a complete model of the THC system for BLDC motor using Si mu link Block. Finally, the simulation and are shown to validate the performance of THC of BLOC motor with improvements of the problem highlighted.
