H/sup /spl infin// preview disturbance attenuation

The performance of preview control is investigated in terms of H/sup /spl infin//-criterion. In the infinite-horizon setting, we define a preview full-information (FI) problem and clarify the solvability and analytic solution in the framework of finite-dimensional operations. The preview FI-problem covers essential part of H/sup /spl infin//-preview problems and enables one to obtain analytic solutions for general problems.
