Abstract
This communication deals with the problem of fault detection for a class of nonlinear systems using unknown input observers. Sufficient conditions for existence and stability of such observers are investigated. Based on linear matrix inequality (LMI) approach a design algorithm is proposed. The procedure includes constraints on detection performances and robustness to unknown inputs. Simulations results applied to a permanent magnet synchronous machine illustrate the potential of the method.
