This study puts forward the problem of fast‐rate fault detection based on multiple slow‐rate sensors. A fast‐rate residual generator with casuality constraint is established from the multi‐sensor model. Parameters of the residual generator are determined via disturbance‐decoupling based on left eigenvector assignment. It is found that the condition of disturbance‐decoupling is related to the multi‐rate sensor sampling nature. A numerical example is given to illustrate the effectiveness of the proposed residual generator.
