Fault-Tolerant Control of Uncertain Linear Systems in the Presence of L∞ Disturbances and Actuator Saturation

In this paper the fault-tolerant control problem for uncertain linear systems in the presence of L∞ disturbances and actuator saturation is studied. The conflict between enlarging the domain of attraction and attenuating the effect of L∞ disturbances is tackled by proposing a non-constant state feedback controller. The feedback gains are calculated off-line by using linear matrix inequalities. In addition, the proposed method is capable of tolerating time-varying faults. The suggested approach is implemented on a sample model and the result is compared with other works.
