Polytope LPV estimation for non-linear flight control

Abstract

AbstractThe current study is motivated by the need to implement the linear based model-based fault detection and isolation (FDI) methodology onto the nonlinear aircraft system directly. The nonlinear model is expressed in the linear parameter varying (LPV) manner and the corresponding LPV FDI estimator can be developed through the combination of the polytopic FDI estimators developed on each system vertex. The proposed design strategy is applied to the nonlinear longitudinal motion of a UAV aircraft (Machan) with different faults acting on the elevator actuator and wind turbulence affecting the vertical force.
