Diagnosis and prognosis of solid oxide cell systems: a statistical approach
Hydrogen is a promising energy carrier in the emerging green energy landscape. It is environmentally friendly, transportable, and storable. The Solid Oxide Cell (SOC) system is a complex technology that enables the bidirectional conversion of hydrogen to energy. The label SOC entails solid oxide fuel cell (SOFC) systems, which produce …
Condition monitoring of mechanical drives: Feature extraction and fault diagnosis methods
Mechanical drives are the most ubiquitous items of equipment in almost all industrial branches. Wear, excessive operational loads or errors in assembly can cause premature unexpected failures resulting in partial or total production downtime, damaged equipment or even loss of lives. Proper condition monitoring of such equipment is therefore of …
Parameter Estimation of Nonlinear Dynamic Systems with Application to Failure Prognostics
This dissertation addresses the problem of parameter estimation of stochastic, discrete-time, state-space models from input and output data. This class of problems can be found in many modern engineering applications, where the relationships in the real world processes have to be inferred from the observed data and available prior knowledge. …
Monitoring of the product quality in manufacturing industries
Unexpected production breakdowns and unpredictable defects in product quality remain critical problems in modern manufacturing systems. Usually occuring by no obvious exterior cause and often during periods of smooth production, they lead to production losses and reduced process availability, which results in lower profit rates. Conventional statistical methods of process …
