In this paper, an adaptive fuzzy approach is proposed to deal with robust output tracking of unknown nonlinear systems with actuator failures. The actuator failures under consideration can be both of lock-in-place and loss of effectiveness. By incorporating fuzzy logic approximation, adaptive algorithm and attenuation technique to our design, a fault tolerant control law is developed to guarantee...
This paper presents a linear matrix inequality (LMI) approach to solve the robust fault-tolerant control problem against actuator failures. Using an equivalent transformation, fault effect factors can be put in Linear Fractional Transformation (LFT) form. While the fault effect factor, such as actuator fault, can be estimated accurately and swiftly, the fault-tolerant control (FTC) problem can be...
This paper deals with the problem of robust fault-tolerant dynamic output feedback controllers design for time-delay systems. The system under consideration involves parameter uncertainties and time-delay. The purpose is to design the dynamic output feedback controller such that, for all admissible uncertainties as well as actuator failures, the system remains stable. The sufficient condition is given...
