Abstract

This paper describes the development of a sliding mode FTC scheme which is based on a LPV system representation. The scheme adopts a model reference framework for tracking capability, and control allocation for automatic control signal redistribution. The paper presents a formal stability analysis and also provides a synthesis framework for the proposed LPV controller. Simulation results based on a high fidelity nonlinear model of a large transport aircraft show good tracking performance in wide variety of flight conditions and in the presence of a class of actuator faults/failures.
