An integrated fault detection, diagnosis and reconfigurable control design method is studied in this paper with explicit consideration of control input constraints. The actuator fault to be treated is modeled as a control effectiveness loss, which is diagnosed by an adaptive algorithm. For fault detection, an observer is designed to generate the output residual and a minimum threshold is set by an H∞ index. To design the reconfigurable controller, an auxiliary matrix is introduced and a linear parameter varying (LPV) system is constructed by convex combination. Linear matrix inequality (LMI) conditions are presented to compute the design parameters of controllers and related performance index. The system performances are measured by the ellipsoidal sets regarding the domain of attraction and disturbance rejection respectively. For illustration, the proposed design techniques are applied to the flight control of a flying wing aircraft under large effectiveness loss of actuators.
