A Study for Improvement of Speed Response Characteristic in Four-Switch Three-Phase BLDC Motor

4스위치 3상 BLDC 전동기의 속도응답특성 향상에 대한 연구

This paper presents a new speed control method using the acceleration feedforward compensation and using the disturbance torque estimate method. The proposed method improve transition response characteristic of system and has been a robust characteristic in the four-switch three-phase motor drive system in which the gain of speed controller cannot be made large enough. The simulation results prove the validity of the proposed method.
