Uncertainties in dynamic systems are an inevitable consequence of non-linearity and complexity, and obscure the performance of fault diagnosis. In order to achieve robust and reliable fault diagnosis, the unknown input (disturbance) de-coupling principle has been employed in recent research. In this paper, a method of computing the unknown input distribution matrix is proposed as a powerful alt...

in this paper, a reaction system consisting of two parallel, non-isothermal autocatalytic reactions in a continuous stirred tank reactor (cstr) has been considered. reactor chaotic behavior is possible for certain values of system parameters. two types of controllers are designed and compared in order to control both the reactor temperature and the product concentration. the first controller is...

This paper focuses on the development of a suitable Fault Detection and Isolation (FDI) strategy for application to a system of inter-connected and distributed systems, as a basis for a fault-tolerant Network Control System (NCS) problem. The work follows a recent study showing that a hierarchical decentralized control system architecture may be suitable for fault-tolerant control (FTC) of a ne...

A state observer is a system that models a real system in order to provide an estimate of the internal state of the system. The design techniques and comparison of four different types of state observers are presented in this paper. The considered observers include Luenberger observer, Kalman observer, unknown input observer and sliding mode observer. The application of these observers to a Mul...

Amongst all these resistive forces in a modern passenger car, depending on the driving conditions and tire specifications, about 20–30% of total fuel consumption is related to rolling resistance. The resistance vehicle still rather unknown research should be conducted able estimate it reliably accurately. This accuracy particularly necessary at scale single reduce consumption, considering that ...

The problem of unknown input observer design is considered for coupled PDE/ODE systems subject to incremental sector bounded nonlinearities and boundary inputs. Assuming available measurements at the distributed domain, synthesis based on Lyapunov methods recast in terms some matrix inequalities. Numerical simulations support confirm theoretical findings, illustrating robust estimation performa...
