In this chapter, the problem of integrated fault detection, isolation, and tracking (IFDIT) control is addresses for linear systems subject to both bounded energy and bounded peak disburbances. A dynamic observer is proposed and implemented by using H_∞/H_/L1 formulation of the IFDIT problem. A single dynamic observer module is designed that generates the residuals as well as the control signals.
