This paper is concerned with the problem of designing adaptive fault-tolerant output-feedback controllers for linear time-invariant (LTI) systems with actuator saturation. By combining the linear matrix inequality (LMI) approach for output-feedback controllers design and adaptive method, a method of designing adaptive reliable output-feedback controllers is proposed, where the controller parameter...
This paper presents an adaptive method to solve the robust fault-tolerant control (FTC) problem for a class of large scale systems against actuator faults and lossy interconnection links. In terms of the special distributed architectures, adaptation laws are proposed to estimate the unknown eventual faults of actuators and interconnections, constant external disturbances, and controller parameters...
In this paper, direct adaptive control schemes are developed to solve the robust tracking problem of a class of distributed large scale systems with actuator faults, faulty and perturbed interconnection links, and external disturbances. The adaptation laws are proposed to update controller parameters on-line when all eventual faults, the upper bounds of the perturbations and disturbances are assumed...
This paper studies the problem of designing adaptive fault-tolerant controllers for linear time-invariant systems with actuator saturation. New methods for designing indirect adaptive fault-tolerant controllers via state feedback are presented for actuator fault compensations. Based on the on-line estimation of eventual faults, the adaptive fault tolerant controller parameters are updating automatically...
This paper studies the problem of designing robust Hinfin filters for linear uncertain systems. The uncertainty parameters are assumed to be time-varying, unknown, but bounded, which appear affinely in the matrices of system models. An adaptive mechanism is introduced to construct novel filters with variable gains, which can reduce the conservativeness of traditional robust Hinfin filters. The proposed...
