The parameter estimation and fault detection of a class of neutral transition systems with time-delay and uncertainty are studied. The error dynamic characteristics including unknown inputs, model uncertainties and time delays are obtained through reconstruction of the system. Fault detection and filtering The existence conditions of the robust fault detection filter are given in the form of linear matrix inequalities.The designed modal fault detection filter makes the system stochastic and stable with good anti-jamming performance and fault detection ability The simulation example shows the effectiveness of the design method.
