Abstract：Present a scheme of designing observer to achieve robust fault diagnosis of redundant servo system, combining eigenstructure assignment with dual theory and state-feedback. By using eigenstructure assignment, the residual is de-coupled from structured disturbance; By using dual theory and state feedback, the residual is de-coupled from interaction of other channels. On the basis of disturbance de-coupling, utilized the design freedom of observer's parameters, the fault is isolated to the greatest extent. Finally, the simulations of two redundant servo systems show the effectiveness of the scheme.
