Abstract	This paper concerns with robust residuals generation such that the designed signatures can be used to isolate actuator faults simultaneously and is not sensitive to exponential autocorrelation stochastic disturbance signal which contaminates one of plant's inputs. The proposed solution of this problem consists of two stages. The first stage is to derive an internal model of stochastic disturbance signal. The internal model is then augmented to the original plant's model so that a new plant's model is obtained. The second stage is to generate a transformation matrix such that each original feature vector of actuator fault is converted into the corresponding designed directional residual with its vector direction as its signature. Based on the designed of signature vectors the modes of residual actuator fault can be decoupled one from others and robust to the stochastic disturbance signal. The transformation matrix is constructed row by row in order each row can block the disturbance signal so that strict robustness can be achieved. To demonstrate the effectiveness of the method a simulation study on a Magnetic -Tape-Drive MIMO system which has multi input and multi output is excuted. The result shows that the method has been successfully implemented.
