摘要

This paper describes the development and evaluation of sliding mode schemes to handle actuator and sensor faults for the RECONFIGURE benchmark problem. For the actuator fault problem, a linear parameter varying (LPV) sliding mode control allocation scheme has been developed. The scheme is retro-fitted to the existing baseline controller. When faults/failures are present in an elevator, the LPV sliding mode activates and re-allocates the control signal to the remaining healthy elevators. For the sensor fault problem, an LPV sliding mode observer (SMO) has been developed in such a way that the effect of uncertainty on the fault reconstruction as well as the effect of the observer-plant mismatch due to uncertain scheduling parameters are minimised. Both schemes have been coded using the AIRBUS graphical library so that they can be directly implemented on an industrial flight control computer. Both schemes are evaluated using Monte-Carlo simulations for various manoeuvres.
