Fault estimation for single output nonlinear systems using an adaptive sliding mode estimator

By Xing-Gang Yan and Christopher Edwards


A class of single output nonlinear systems with an uncertain parameter is considered. A diffeomorphism\ud is first introduced to simplify the system structure, then, by employing an adaptive approach to identify the\ud unknown parameter, a sliding mode approximate estimator is developed to estimate the system state\ud variables. Based on the estimator, a fault estimation scheme is proposed together with an approach to\ud optimise the estimation error using linear matrix inequality techniques. A simulation example is given to\ud demonstrate the proposed scheme
