Water-Level Control for the U-Tube Steam Generator of Nuclear Power Plants Based on Output Feedback Dissipation

Output Feedback Dissipation Control for the Power-Level of Modular High-Temperature Gas-Cooled Reactors

“…From Equations (29) and (30) (15) is zero-state detectable and equation (16) is satisfied, then control law (25) guarantees the globally asymptotic closed-loop stability if ξ des satisfies (19) and positive scalar F is large enough.…”

“…In the second step, the emanative part of the dynamics is restrained by feedback for asymptotic closed-loop stability [20][21][22]. This control theory has been successfully applied to power system regulation [23], nuclear reactor state-observation [24], water-level control of U-tube steam generators (UTSGs) [25], etc. Since the dynamics of the HTR-PM are highly nonlinear, and the system parameters also vary with the power-level extensively, it is quite necessary to design a simple power-level regulator which guarantees globally asymptotic closed-loop stability.…”

Dissipation-Based High Gain Filter for Monitoring Nuclear Reactors

“…From (11), and Subtract (21) from (20), and then the GHR of the error dynamics (15) can be written as (25) where (26) (27) and (28) Based on (18) and (19), differentiate Hamiltonian function along the trajectory given by error dynamics (25),…”

“…Cheng et al studied the question of feedback equivalence from nonlinear systems to PCH systems, and gave conditions under which a general nonlinear system can be transformed into a PCH system via static state-feedback [16]. Though PCH control system theory has been proved to be a promising technique of designing stabilizing regulators for nonlinear systems [17]- [25], there is still no state-observer established based on this theory. Moreover, it is well known that state-observer is so crucial to monitoring nuclear reactors that it can not only reconstruct all the state variables of nuclear reactors from available measurements but also give reference signals for FDI of nuclear reactors.…”

Particle Swarm Optimization to the U-tube steam generator in the nuclear power plant

“…So, a need for the performance improvement in the existing water level regulators is obvious. Many advanced control methods such as adaptive predictive control (Parlos and Rais, 2000;Ahmed and Al madani, 2002); fuzzy logic control (Dong et al, 2009), model predictive control (Parlos and Rais, 2000;Campana et al, 2006); optimal control (Gee Han, 2000) and combination of these control methods (Na, 2003;Shi and Liang, 2007) have been suggested to resolve the UTSG water level control problem.
