Abstract

This paper proposes an estimation algorithm to find the moment of inertia, which is essential to design high performance controller for motor drive system. The algorithm finds the moment of inertia observing the position error signal, which contains an error information of moment of inertia, generated by speed observer. Moreover, the proposed algorithm is easily realized in the observer-based speed detection method. The simulation and experimental results are also presented to confirm the performance of moment of inertia estimation method, which shows that the moment of inertia converges to the actual value within several seconds. The speed control responses and the designed speed controller performance match well.

본 논문에서는 전동기의 고성능 속도제어를 위해 필수적인 상수인 관성을 추정하는 알고리즘을 제안한다. 제안된 알고리즘은 속도관측기에서 발생되는 관성오차의 정보를 포함하고 있는 위치 오차신호를 관측하여 이를 비례적분 제어기를 사용하여 정상상태 오차를 없게 제어함으로써 관성을 추정하므로 특히, 관측기 기반 속도측정법에 쉽게 구현이 가능하다. 모의실험과 실험결과를 제시하여 추정관성이 제안된 방법에 의하여 실제값에 수렴하였으며 이에 파라 관측된 속도 역시 실제 측정된 속도와 일치하게 되었으며, 속도제어기가 설계한 응답특성을 보임을 입증하였다.
