Bang-bang Controls and Piecewise Constant ones for Continuous Roesser Systems

In the paper, we prove the bang-bang principle for a continuous linear nonautonomous Roesser system and some approximation result (with respect to piecewise constant controls) for a continuous nonautonomous Roesser system which is linear in the state and nonlinear in the control.
