초록

본 논문은 BLDC 전동기의 속도제어를 위해 백스텝핑 설계기법을 이용한 제어기 설계방법을 제안한다. 먼저 백스텝핑 설계기법으로 제어기를 기반으로 부하토크의 추정기를 설계한다. 부하토크의 추정기는 부하토크 변동에 대해 실시간 추정할 수 있도록 구성되어졌다. 제안된 제어기를 120W급의 BLDC 전동기에 적용하여 부하토크를 실시간 적응하면서 속도 레퍼런스를 추종하는 능력을 시험하였다. 그 결과 설계된 제어기와 추정기의 성능이 유용함을 보일 수 있었다.

In this paper, we propose a method that can be used to back-stepping controller design for speed control of Brushless Direct Current (BLDC) motor. First, back-stepping controller is designed with load torque estimator. The estimator is included to adapt to the variation of load torque in real time. Finally, the proposed controller is tested through experiment with a 120W BLDC motor for the angular velocity reference tracking performance and load torque volatility estimation. The simulation result verifies the performance of the proposed controller.
