초록

본 논문에서는 영구자석 동기전동기의 운전중 간섭성분을 형성하는 고정자 인덕턴스가 변화할 경우 d축 전류의 오차로부터 고정자 인덕턴스의 변화량을 보상할 수 있는 보상기를 제안하였다. 그리고 이러한 보상기를 기존의 DDC(Dynamic Decoupling Control)에 적용하여, 고정자 인덕턴스의 변화에 대한 강인성이 향상된 비 간섭 전류제어기를 설계하였다.

This paper proposes a improved decoupling current control algorithms using a compensator to enhance the robustness to the stator inductance error. And the compensator composed from a d-axis current error for sensing change of the real stator inductance can match the estated stator inductance to the real stator inductance. A great advantage of this algorithms is more robust than feedforward decoupling current control or dynamic decoupling control. So it looks suitable to the practical applications where the exact parameters are unknown. Though simulation and experimental results with 1[kW] prototype PMSM and TMS320F2812 board for motor control, we show that the proposed controller achieves the desired performance.
