Fault Diagnosis in Dynamic Systems via State Estimation - a Surveye commonly used techniques of hardware redundancy these methods make use of analytical redundancy and, thereby, allow to detect and localize faults with the aid of a digital computer. They comprise single, multiple or hierarchical state estimation using Luenberger observers or Kalman filters. An iss

A Distributed Hypothesis-Testing Team Decision Problem with Communications Costers (DM’s); one is refered to as the primary DM and the other as the consulting DM. The team objective is to carry out binary hypothesis testing based upon uncertain measurements. The primary DM can declare his decision based only on its own measurements; however, in ambiguous situations the primary

Composite Observers for Failure Detection in Multivariable Multi-Time Scale Systemslobal system, with overlapping transformations on the slow variables. This decomposition applied simultaneously with the singular perturbations method allows to build composite decentralised observers and to identify malfunctioning sensors. A comparison is made on an example between failure detectio

Sensor Fault Detection via Robust Observersof the paper shows a design procedure for a discrete time observer which considers the concept of the “invariant subspace” and of the “almost invariant subspace”. Design tool is the Kronecker canonical form which also gives a complete answer to the question of state estimation of discrete time syste

Diagnosability and Failure Detection in Linear Discrete Dynamical Systemsd discusses the detectionability. We find that a weakly-diagnosable-space can exist for dynamics failure rather than for sensor one. To overcome the problem, two extended GLR methods are next developed, that is, the one making use of another reduced-order GLR method which has effect for the anomaly

Fault Diagnosis in Dynamic Systems Using a Robust Output Zeroing Design Methodor fault diagnosis. The design uses a robust observer in which the weighted linear combination of m estimation errors is equivalent to the output zeroing problem. In order to design a fault monitor which is insensitive to r (multivariable) input and parameter-induced disturbances, n-1 eigenvectors a

Validation of Measurements in Control System by Means of Analytical Redundancyerarchy. Accordingly, the necessity to validate the measurements leads to supervision structures which use physical and/ or analytical redundancy of the sensors. Analytical redundancy uses the system’s model in order to generate statical or dynamical relationships linking the values of the measured

Fault Detection and Location in Mrac Robotic Systemsrence Adaptively Controlled (MRAC) robotic systems is investigated. The MRAC model assures convergence to suitable reference models for a class of processes, one of which is the manipulator. However, sudden changes, modelled as faults, in the process parameters may lead to degradation of performance

Design of Fail-Safe Tunable Digital Set-Point Tracking Controllers for Multivariable Plantsuator failure associated with any one of the manipulated variables. The effectiveness of such a tunable digital controller is illustrated by designing a ‘fail-safe’ tunable set-point tracking controller for a multivariable plant with two outputs and three manipulated variables.

The Design and Assessment of a Sliding Mode Controller for the Lateral Motion Model of an Aircraften. The linear and non-linear model responses are compared when subjected to the same variable structure control design. It is shown that, after sliding has commenced the response of the objective system is tracked by the corresponding nonlinear system. A measure of sensitivity is defined as the pro
