We prove that the trajectory attractor U of the 3D magnetohydrodynamic- model converges to the trajectory attractor U0 of the 3D magnetohydrodynamic system (in an appropriate topology) when approaches zero.enAmerican Institute of Mathematical Sciences (AIMS)Magnetohydrodynamic-alpha modelTrajectory attractorMagnetohydrodynamic equationsNavier-Stokes equationsApproximation of the trajectory attractor of the 3D MHD systemPostprint Article
