Model-based process supervision: a bond graph approach
Samantaray, A.K.
Bouamama, B. Ould
The authors use bond graph (BG) modelling, a unified multi-energy domain method, to build dynamic models of process engineering systems; BG sub-models for various common process engineering devices are developed. The structural and causal properties of BG models are exploited for supervisory systems design. Controllability and observability are elegantly derived from BG models by following the simple algorithms presented here. The design and resource optimizationof new supervision platforms is aided by analysing model structure to determine how easy it will be to detect and/or isolate some specific sub-space of theprocess. Real-time evaluation of system contstraints followed by various decision steps integral to the supervisory environment are used to extract meaningful data from process state knowledge. Several applications to academic and small-scale-industrial processes are discussed and the development of a supervision platform for an industrial plant is presented with experimental validation. Use of bond graphs to model industrial processes for supervision speeds up validation of design control design aspects like sensor/actuator placement Automatic generation of algorithms to monitor processes in healthy and faulty operation Genuine integrated design uses a common modelling tool for process simulation, control analysis and fault detection and isolation INDICE: Introduction to Process Supervision.- Bond Graph Modelling in Process Engineering.- Model-based Control.- Bond Graph Model-based Qualitative FDI.- Bond Graph Model-based Quantitative FDI.- Application to a Steam Generator Process.- Diagnostic and Bicausal Bond Graphs for FDI.- Actuator and Sensor Placement for Reconfiguration.- Isolation of Structurally Nonisolable Faults.- Multiple Fault Isolation through Parameter Estimation.- Fault Tolerant Control.
