Abstract :
In this paper the problem of robust structure residual design based on unknown input observer is studied. For the residual set lying in a fixed and fault-specific direction in the residual space in response to each fault, a new residual vector generation method based on residual space identification is presented, and the detail simulation example demonstrate validity and efficiency.
