Based on system simulation, a new approach on fault detection and identification (FDI) is suggested in this paper. The logical structure of FDI is built on system simulation process, in which the bias of theoretical trajectory is cut down by interactive mutual information. Under the multi-input multi-output system and dynamic-measurement system, a series of identification algorithms are given, which can be used to solve the following problem, such as fault detection, fault identification, estimation of f...
