Abstract

In this paper, the water level control problem of U-Tube Steam Generators (UTSG) of Nuclear Power Plants is investigated. A design approach for the piecewise gain-scheduled observer-based H_∞ controllers is presented subject to power adjustments via discrete-time linear parameter-varying framework, in terms of linear matrix inequalities. The desired controllers can guarantee asymptotic stability and H_∞ performance of the resulting closed-loop systems in each operation region. Detailed design and simulation process are described based on Irving UTSG model. The simulation results demonstrate the novelty and effectiveness of the proposed approaches.
