Numerical computation of H/sup /spl infin//-optimal control for distributed parameter systems

Solves the H/sup /spl infin//-optimal mixed sensitivity problem for distributed parameter single-input/single-output systems directly from problem data, via numerical techniques. These results expand upon previous related work of the authors involving a new norm on the frequency response, and present a partial answer to the question of the sufficiency of frequency response data for design purposes. This work also shows that certain H/sup /spl infin// problems are indeed well-posed, under reasonable assumptions on the roll-off of the frequency response.< >
