Résumé

This discussion paper provides a solution for the aerospace industrial fault detection and fault-tolerant control competition. This study deals with a model-based method for robust and early detection of Oscillatory Failure Cases (OFC) in aircraft control surface servo loops and a control reconfiguration algorithm in the flight control system. An improved model-based monitoring approach is presented, based on a nonlinear actuator model, band-pass filters, sliding windows, and an adaptive threshold generator. The results are promising and show that the proposed scheme is able to detect any OFC signal with a very low false alarm rate. In addition, a simple incremental active disturbance rejection control (ADRC) reconfiguration is proposed, starting from a transient trajectory generator, to arrange a smooth and quick transition from the normal law to the alternate law after the detection of OFC. Validation is achieved using the industrial benchmark jointly proposed by Airbus and Stellenbosch University
