Mathematical modeling of control system for the experimental steam generator

Evolved Fuzzy Control System for a Steam Generator

Poor control of steam generator water level is the main cause of unexpected shutdowns in nuclear power plants. Such shutdowns are caused by violation of safety limits on the water level and are common at low operating power where the plant exhibits strong nonminimum phase characteristics. In addition, the steam generator is a highly complex, nonlinear and time-varying system and its parameters ...

Steam Generator Water Level Control: a Hybrid System Approach

The Mixed Logical Dynamical (MLD) formalism is an efficient modeling framework for hybrid systems which allows formulating and solving problems such as moving horizon predictive control and state estimation. This paper presents the application of the combined strategies – state estimation for fault detection and predictive control for water level control – to a steam generator benchmark modeled...

Numerical Modeling of Eddy Current Steam Generator Inspection: Comparison with Experimental Data

An EMAT System for Detecting Flaws in Steam Generator Tubes

The detection of flaws in steam generator tubing is often made difficult by environmental considerations. The small diameter, 7/8 inch (2.2 cm), long, 70 feet (21.3m), tubes occur in large bundles with access only being possible from the inside of the end of each tube. Furthermore, inspection must be fully automatic when the steam generator is part of a nuclear power plant because of radiation ...
