For a general H/sub 2/ optimal control problem, first all H/sub 2/ optimal measurement feedback controllers are characterized and parameterized. The H/sub 2/ optimal control problem with strictly proper controllers and the H/sub 2/ optimal control problem with proper controllers are essentially different and hence clearly delineated. Next, estimator based H/sub 2/ optimal controllers are characterized and parameterized. Also, systematic methods of designing them are presented. Since in general there exist many H/sub 2/ optimal measurement feedback controllers, utilizing such flexibility and freedom, one can place the closed-loop poles at more desirable locations while still preserving H/sub 2/ optimality. All the design algorithms developed here are easily computer implementable.
