초록

In this article, an optimal control problem associated with convection-diffusion equation is considered. Using Lagrange multiplier,the optimality system is obtained. The derived optimal system becomes coupled, non-symmetric partial differential equations. For discretizations and implementations, the finite element multigrid V -cycle is employed. The convergence analysis of finite element multigrid methods for the derived optimal system is shown. Some numerical simulations are performed.

Abstract

In this article, an optimal control problem associated with convection-diffusion equation is considered. Using Lagrange multiplier,the optimality system is obtained. The derived optimal system becomes coupled, non-symmetric partial differential equations. For discretizations and implementations, the finite element multigrid V -cycle is employed. The convergence analysis of finite element multigrid methods for the derived optimal system is shown. Some numerical simulations are performed.
