Systems with input or output delays form the simplest, and yet one of the most widely applied classes of distributed parameter models. This is a review of some problem-oriented H
methods for that class, with an emphasis on computational simplicity. Reviewed methods include operator interpolation, game-theoretic state-space treatments in the time domain, a J-spectral factorization approach, and methods exploiting various ideas from sampled-data theory. Some interesting properties of the (sub) optimal solution are discussed as well.
