In this paper, a diagnosis method for time-delay fractional systems is developed. The fault detection and isolation are ensured by the use of a bank of unknown input fractional observers. Theoretical development leads to the obtention of the observer parameters in order to engender structured residuals. A numerical example illustrating the validity of the method in fault detection and isolation is...
Electric Power Steering (EPS) is an advanced steering system that consists of two subsystems: electrical and mechanical subsystems. EPS systems not only provide steering assist to drivers but they are also actuators for recently developed active safety features, such as lane keeping and lane changing assist. Failure of some component of the EPS system can lead to walk-home situations and increased...
The purpose of this paper is to provide new methods for neutral system stability and diagnosis analysis. Based on Kharitonov stability, a new theorem is proposed for delay neutral system with robust control. For stabilized neutral system, an unknown input observer with new structure is then investigated to diagnosis this type of system. Tow important conditions are presented to can apply this type...
Commercial off the shelf (COTS) equipment is generally preferred because of its low acquisition costs, wider user base and implied support from the vendor. Because it is treated as a black box, however, it is often complicated to measure the testability and diagnosability of the COTS equipment and therefore its supportability is difficult to predict. While some metrics for testability, diagnosability...
Control system of a condensation turbine with fault tolerant instrumentation lines is presented in this paper. The characteristics of instrumentation signals entering the controller and methods of fault detection are also presented. Application of modelling for diagnostic purposes is given. The creation of partial models used for fault detection as well as methods of fault isolation are described.
