Abstract

This paper deals with the estimation of unknown actuator faults for linear dynamic systems with sensor noise. The presented method based on the PI(proportional-integral) observer permits to achieve good convergence and exact estimation of unknown faults. The validity of proposed method is established with simulation results and comparisons to the existing methods.

본 논문에서는 센서잡음이 있는 선형계의 구동기에 도입되는 미지고장을 추정하는 방법에 대해 연구하였다. 구동기의 미지 고장추정을 위하여 새로운 PI관측기를 도입함으로써 기존의 추정 방법에 비해 추정 성능을 개선시킬 수 있었으며, 시뮬레이션 결과로부터 본 연구방법의 유용성을 입증할 수 있었다.
