One-side exact controllability and observability for quasilinear hyperbolic systems

摘要

The known theory on the one-side exact boundary control lability and the one-side exact boundary observability for first-order quasilinear hyperbolic systems requires that the unknown variables should be suitably Coupled in the boundary conditions at the non-control or non-observation side. In this Note we illustrate, with an inspiring example, that the one-side exact boundary control lability and the one-side exact boundary observability can still be realized by means of a suitable coupling among the unknown variables in the quasilinear hyperbolic system itself.
