By means of two\-dimensional\/repetitive setting, the sufficient conditions for batch\-to\-batch error convergence and $\\mathcal\{H\}_\{\\infty\}$ disturbance attenuation are formulated and analyzed. Subsequently, the procedure for computing the desired control law matrices is formulated in terms of solvability of linear matrix inequalities."]
