Optimal control of n × n parabolic system involving time lag

Show Summary Details


In this paper, we study the optimal control problem for an n × n coupled system of second-order parabolic partial differential equations with infinitely many variables and constant time lag. Making use of the Lions scheme (Lions, 1971, Optimal Control of Systems Governed by Partial Differential Equations), necessary and sufficient condition of optimality for the Neumann problem with quadratic performance functional and constraint control is derived. Finally, several mathematical examples for derived optimality conditions are presented.
