Through designing a proper residual generator and implementing the decoupling of the residuals from system inputs and measurement disturbances, the residuals reflect the fault detection status. By applying space division to the unobservability subspace, the structured residual set is established, which is exactly corresponding to fault set, and therefore the fault isolation is achieved. Finally, simulation examples show the feasibility and effectiveness of the presented algorithm.
