摘要:

The H∞optimal controller for 1-block problems is shown to have a McMillan degree bound of n, where n is the degree of the plant. An example is given where the bound is attained. The result follows simply from the work of Limebeer and Anderson (1987) and Limebeer and Hung (1987), who (because of a small oversight) derived a bound of n - 1. Problems for which the bound is n - 1 are characterized.
