Abstract  The dual formulation of the discrete-time mixed l2/l1 control design problem was achieved by using the duality theory of Lagrange multipliers. For some special dual mixed l2/l1 problems, an approximation method for the optimal value is introduced. A suboptimal value of the infinite-dimensional dual problem can be obtained by solving a sequence of truncated problems. The convergence property of the solution scheme is investigated. This paper gives a low approximation method for the primal problem.

Key words： mixed l2/l1 control      approximate analysis      lagrange multiplier theory
