High-order well-balanced methods for systems of balance laws: a control-based approach

作者:

Highlights:

• A general strategy to design high-order well-balanced finite volume methods is introduced.

• Stationary solutions with given averages have to be found at every cell in the reconstruction procedure.

• The key idea is to solve these local problems by using techniques of the control theory.

• The strategy is applied to some 1d systems of balance laws including the shallow water equations.

• Accurate methods that preserve moving stationary solutions for Euler equations with gravity are obtained.
