Brushless DC Motor 속도 추종을 위한 토크 변조 기법
나누리(Nuri Na),전홍찬(Hongchan Jeon),이영우(Youngwoo Lee) 대한전기학회 2021 전기학회논문지 P Vol.70 No.3
In this paper, velocity control using torque modulation is proposed for Brushless DC motor. Torque modulation is designed to improve velocity tracking performance based on error dynamics. Lyapunov based current controller is developed to tracking desired currents generated from desired torque, which is calculated based on torque modulation scheme. Closed-loop stability is proven by Hurwitz’s theorem. Simulations are performed to evaluate the effectiveness of the proposed method.
