H/sub infinity / type problem for sampled-data control systems-a solution via minimum energy characterization

A solution for an H/sub infinity / type problem for sampled-data control systems is derived. The solution is given in terms of an equivalent discrete-time H/sub infinity / problem. The reduction procedure is described and characterized from the viewpoint of the minimum energy principle and J-unitary transformations, which turn out to be more straightforward than the existing methods.<
