Minimal time for the exact controllability of one-dimensional first-order linear hyperbolic systems by one-sided boundary controls (1901.06005v2)
Published 17 Jan 2019 in math.OC and math.AP
Abstract: In this article we study the minimal time for the exact controllability of one-dimensional first-order linear hyperbolic systems when all the controls are acting on the same side of the boundary. We establish an explicit and easy-to-compute formula for this time with respect to all the coupling parameters of the system. The proof relies on the introduction of a canonical $UL$-decomposition and the compactness-uniqueness method.
