Controllability for trajectories of semilinear functional differential equations

Jin-Mun Jeong, Yong Han Kang

Abstract

In this paper, we first consider the existence and regularity of solutions of the semilinear control system under natural assumptions such as the local Lipschtiz continuity of nonlinear term. Thereafter, we will also establish the approximate controllability for the equation when the corresponding linear system is approximately controllable.

Keywords: approximate controllability, semilinear control system, local lipschtiz continuity, controller operator, reachable set
