Hardware-in-the-loop simulation for a sliding mode FDI scheme

Abstract

This paper describes the implementation of a sliding mode observer based fault detection and isolation (FDI) scheme, which is capable of reconstructing/estimating sensor faults, on the Japan Aerospace Exploration Agency's Multi-Purpose Aviation Laboratory (mathbf{MuPAL}-alpha)research aircraft. Hardware-in-the-loop (HIL) simulation results, which serve as a precursor to upcoming real test flights, are presented in this paper. The HIL simulation results show good yaw rate sensor fault reconstruction performance, and will be flight tested as the next stage of development and validation.
