abstract = {This paper considers Faut Tolerant Control (FTC) problem for discrete-time Linear Time-Invariant systems (LTI) affected by faults on actuator. First, zonotope-based interval estimation technique is proposed, which integrate robust observer design with zonotopic analysis. By introducing H∞ performances in the observer design, the designed technique reduce the effects of uncertainties and improve the interval estimation accuracy. Based on the robust designed observer, the interval state estimation can be realized via a zonotopic analysis. Second, a FTC is designed to stabilize the close-loop system subject to actuator faults. The control law design is based on zonotopic technique, guaranteeing closed-loop stability. Simulation results are provided to illustrate the performance of the proposed method. © 2021 IEEE.},

abstract = {In this paper, a Passive Fault Tolerant Control (PFTC) strategy for Linear Time Invariant (LTI) systems subject to actuator faults is proposed. The idea of this PFTC method is to compute a control law to cope with additive actuator faults using interval observers. The considered system is assumed to be subject to bounded noises and disturbances without any additional assumptions. The FTC is implemented as a state linear feedback control and designed using interval observers techniques. A numerical example shows the efficiency of the proposed technique. © 2016 EUCA.},
