This paper deals with guaranteed state estimation for a large class of nonlinear continuous-time systems in a bounded error context. The proposed observer is based on a guaranteed Linear Parameter-Varying (LPV) approximation of the original nonlinear model. The linearisation is justified since it is difficult to develop generic methods for computing a stable observer for a nonlinear system. The Luenberger...
A novel non-linear observer for detection of oscillatory faults in commercial airplanes is proposed in this work. Oscillatory Failure detection in airplanes is an important problem because of natural mode excitation and the structural loads they can provoke. A simple and novel non-linear observer with two correction terms is developed. Formal proof of stability and convergence of the observer in the...
