In this paper, a novel fault detection and isolation filter design method for power distribution in DC electronic system is proposed. The proposed double filter method is a combination of quadratic programming (QP) and Kalman filter which has three main advantages: first, it could estimate the fault position accurately under non-white noise. Second, this is a sequential method which could be used for real-time fault estimation with limited computation. Third, the model is simple and could be used on other circuits without much effort. The performance of the proposed method is verified by numerical simulations.
