Nonlinear dynamic systems and optimal control problems on time scales
This paper is mainly concerned with a class of optimal control problems of systems governed by the nonlinear dynamic systems on time scales. Introducing the reasonable weak solution of nonlinear dynamic systems, the existence of the weak solution for the nonlinear dynamic systems on time scales and its properties are presented. Discussing -strong-weak lower semicontinuity of integral functional, we give sufficient conditions for the existence of optimal controls. Using integration...
