In this paper, operator based fault tolerant control for uncertain nonlinear system with actuator fault is considered by using operator based robust right coprime factorization approach. In detail, on the basis of the operator based control design structure, fault detection system design and fault tolerant control system design are considered for nonlinear system without and with uncertainty, respectively...
In this contribution, we present initial developments in view of model-based fault-tolerant control (FTC). In this context, we use an original method based on the Kalman-filter by which fault detection, diagnosis and accommodation is possible provided that an accurate model is available. Since this is not generally true, we attempt to alleviate this necessity by means of accounting for uncertainty,...
The problem of integrated fault diagnostic and fault-tolerant control for uncertainty linear system is developed. Focusing on the actuator and sensor faults of satellite, we presents a fault diagnosis method based on sliding mode observer. And considering the uncertainties of diagnosis results, we also design a Hinfin state-feedback controller to achieve the fault-tolerance by solving a linear matrix...
The implementation of complex functionality in low-power nano-CMOS technologies leads to enhance susceptibility to parametric disturbances (environmental, and operation-dependent). The purpose of this paper is to present recent improvements on a methodology to exploit power-supply voltage and temperature variations in order to produce fault-tolerant structural solutions. First, the proposed methodology...
