Residual Bond Graph Sinks for Numerical Evaluation of Analytical Redundancy Relations in Model Based Single Fault Detection and Isolation
نویسنده
چکیده
The paper proposes a bond graph approach to model based fault detection and isolation (FDI) that uses residual sinks. These elements couple a reference model of a process engineering system to a bond graph model of the system that is subject to disturbances caused by faults. In this paper it is assumed that two faults do not appear simultaneously. The underlying mathematical model is a Differential Algebraic Equations (DAE) system. The approach is illustrated by means of the often used hydraulic two tanks system. Keywords— Bond Graph models for fault detection and isolation, analytical redundancy relations, residual sinks, DAE systems.

Diagnosis of Switching Systems using Hybrid Bond Graph
Hybrid Bond Graph (HBG) is a Bond Graph-based modelling approach which provides an effective tool not only for dynamic modeling but also for fault detection and isolation (FDI) of switching systems. Bond graph (BG) has been proven useful for FDI for continuous systems. In addition, BG provides the causal relations between system’s variables which allow FDI algorithms to be developed systematica...
متن کاملDiagnostic bond graphs for online fault detection and isolation
Analytical redundancy relations (ARR) are symbolic equations representing constraints between different known process variables (parameters, measurements and sources). ARR are obtained from the behavioural model of the system through different procedures of elimination of unknown variables. Numerical evaluation of each ARR is called a residual, which is used in model based fault detection and i...
متن کاملImprovements to Single-Fault Isolation Using Estimated Parameters
A method for finer fault isolation or localization in the model based fault detection and isolation (FDI) paradigm is developed using parallely computed bond graph models. Many of the existing model based FDI methods are based on the evaluation of model consistency expressed in terms of analytical redundancy relations (ARR). These evaluations lead to residuals, and a number of sensors are to be...

The method of Bond Graph based Analytical Redundancy Relations in Fault Detection and Isolation is explicitly associated with components faults, this is due to architectural and functional aspect of the Bond Graph tool. This allows using the reliability of each component to improve the decision-making step. The purpose of this paper is the improvement of the classical binary method of decision-...
