In this article, global stabilization results for the two dimensional viscous Burgers' equation, that is, convergence of unsteady solution to its constant steady state solution with any initial data, are established using a nonlinear Neumann boundary feedback control law. Then, using C 0 -conforming finite element method in spatial direction, global stabilization results for the semidiscrete solution are shown. Moreover, optimal error estimates in L ∞ (L 2 ) and in L ∞ (H 1 )norms for the state variable and convergence result for the boundary feedback control law are derived. All the results preserve exponential stabilization property. Finally, several numerical experiments are conducted to confirm our theoretical findings.
