Abstract :
A new approach to the conversion of the sampled-data H∞ problem to an equivalent pure discrete-time, lumped-variables counterpart, is presented. The approach is independent of controller causality constraints. In particular, it is applicable to problems, such as preview tracking and fixed-lag smoothing, where existing reduction methods fail. We demonstrate this by presenting a way to solve open problem no. 5l from V.D. Blondel (1999).
