과도 응답 특성을 개선한 외란 관측기를 이용한 IPMSM의 강인제어

다국어 초록 (Multilingual Abstract)

In order to control IPMSM, a nonlinear control system must be designed and robustness against disturbance is required. In this paper, we propose a new state-based disturbance observer that removes the disturbance and improves the transient response characteristics of IPMSM. The new disturbance observer improves control performance by determining the Lyapunov candidate function by considering both the error of the nominal system and the disturbance estimate simultaneously. Since IPMSM does not satisfy the matching condition, it uses the backstep method that uses the state of the system. Through simulation, we prove that the newly proposed DOB-based controller effectively controls IP MSM.
