This paper studies the integrated fault detection and control problem for linear parameter‐varying systems. A parameter‐dependent detector/controller is designed to generate two signals: residual and control signals that are used to detect faults and simultaneously meet some control objectives. The low‐frequency faults and certain finite‐frequency disturbances are considered. With the aid of the newly developed linearization techniques, the design methods are presented in terms of solutions to a set of linear matrix inequalities. A numerical example is given to illustrate the effectiveness of the proposed methods. Copyright © 2008 John Wiley & Sons, Ltd.
