Fault Tolerant Control Design Using IMM Filter with an Application to a Flight Control System

IMM 필터를 이용한 고장허용 제어기법 및 비행 제어시스템에의 응용

In this paper, an integrated design of fault detection, diagnosis and reconfigurable control tot multi-input and multi-output system is proposed. It is based on the interacting multiple model estimation algorithm, which is one of the most cost-effective adaptive estimation techniques for systems involving structural and/or parametric changes. This research focuses on the method to recover the performance of a system with failed actuators by switching plant models and controllers appropriately. The proposed scheme is applied to a fault tolerant control design for flight control system.
