Abstract

This paper proposes a fault-tolerant control (FTC) scheme for linear parameter-varying (LPV) systems based on integral sliding modes (ISMs) and control allocation (CA) and describes the implementation and evaluation of the controllers on a 6-degree-of-freedom research flight simulator called SIMONA. The FTC scheme is developed using an LPV approach to extend ideas previously developed for linear time-invariant systems, in order to cover a wide range of operating conditions. The scheme benefits from the combination of the inherent robustness properties of ISMs (to ensure sliding occurs throughout the simulation) and CA, which has the ability to redistribute control signals to all available actuators in the event of faults/failures.
