摘要: The present article is concerned with the Neumann control of systems modeled by scalar or vector parabolic equations reaction-advection-diffusion type a particular emphasis on which are unstable if uncontrolled. To solve these problems, we use combination finite-difference methods for time discretization, finite-element space and conjugate gradient algorithms iterative solution discrete problems. We apply then above methodology to test problems in two dimensions, including related nonlinear models.
