For estimating faults of the system with unknown nonlinear term, a novel fault diagnosis method based on nonlinear compensation term and proportional multiple-integral observer is proposed. In this method, the nonlinear compensation term is constructed by support vector machines (SVM), which can reduce the influence of unknown nonlinear part. Proportional multiple-integral observer based nonlinear compensation term can estimate actuator faults when there are sensor faults or output disturbance in the system. The proposed method is applied in civil aircraft system. Simulation experiments are given to demonstrate the efficiency.
