A framework for the joint design of sensor scheduling and fault isolation is proposed. First, the synthesis of fault isolation filter and the communication sequence that ensures the isolability of fault is given. The proposed filter can be viewed as a special structure of the traditional Kalman filter. Several sensor scheduling strategies are proposed in order to ensure the minimization of the noise effect on the generated residual. A numerical example illustrates the effectiveness of the proposed approach.
