Abstract

The main contribution of this paper consists in solving the problem of fault tolerant control (FTC) for linear parameter varying (LPV) systems subject to actuator saturation and fault detection and isolation (FDI) delays. The FTC is based on virtual actuators that reconfigure the faulty plant to maintain the stability and to avoid the saturation of the actuators. On the other hand, a design methodology that provides the nominal output-feedback controller, which maximizes the tolerated delay between the fault occurrence and its isolation, is developed. The design process consists in finding the optimal feasible solution to a finite set of linear matrix inequalities (LMIs). Finally, an example is used to illustrate the theoretical results.
