Abstract

In this paper, we propose a design method for the position and speed controller, current control of a Brushless Direct Current(BLDC) motor using back-stepping design techniques. Further, to stabilize the whole system, and proposes a method for setting the appropriate gain control to improve the tracking performance. By applying the proposed controller to 120W BLDC motors were tested for the ability to follow the position, velocity and current reference. Since the simulation results of the steady state error is within 1%, we were able to show the usefulness of the tracking performance of the proposed controller.

본 논문은 백스텝핑 설계기법을 이용하여 BLDC 전동기의 위치 및 속도, 전류제어를 위한 제어기 설계방법을 제안한다. 또한, 전체 시스템을 안정화하며 추종성능을 향상시킬 수 있는 적절한 제어이득을 설정하기 위한 방법을 제시한다. 제안된 제어기를 120W급의 BLDC 전동기에 적용하여 위치, 속도 및 전류 레퍼런스를 추종하는 능력을 시뮬레이션 시험하였다. 설계된 제어기가 정상상태의 오차가 1% 이내를 가짐으로 상태 추종 성능에 대해 유용한 제어기임을 보일 수 있었다.
