Gas Turbine Modeling for Diagnosis and Control

Abstract: The supervision of performance in gas turbine applications is crucial in order to achieve: (i) reliable operations, (ii) low heat stress in components, (iii) low fuel consumption, and (iv) efficient overhaul and maintenance. To obtain a good diagnosis of performance it is important to have tests which are based on models with high accuracy. A main contribution is a systematic design procedure to construct a fault detection and isolation (FDI) system for complex nonlinear models. To fulfill the requirement of a… Show more

“…Here, in order to eliminate the inconvenience stated above, the health parameters for gas path components can be redefined using component similar performance parameters (e.g., corrected mass flow rate /  for compressor and turbine), where the same treatment can be found in the treatment of characteristic maps for compressor and turbine [5].…”

“…Condition-monitoring plays an increasingly important role for technical processes in order to improve reliability, availability, maintenance and lifetime of equipment [3]. The detection of engine performance and gas path performance analysis are considered to be effective approaches to enhance the reliability and safety of the turbofan engine [4,5]. Additionally, the detection systems can also be used for the scheme of on-condition maintenance for the purpose of decreasing the maintenance costs [6].…”
