摘要
本文描述了Ｈ２ 性能约束下的离散控制系统ｌ１ 设计问题，并提出了该无穷维优化问题的一种上逼近解法，通过求解一系列的截断问题能够得到无穷维问题的次优解，混合ｌ１／ Ｈ２ 问题最优值对Ｈ２
A discrete time l 1 control design problem involving a constraint on H 2 performance is formulated and an upper approximation method for the solution of this infinite dimensional optimization problem is introduced.Suboptimal solutions of the problem can be obtained by solving a sequence of truncated problems.The continuity property of the optimal value with respect to changes in the H 2 constraint is studied.
