摘要: The suboptimality of some parameter for H/sub infinity /-optimization by dynamic state-feedback is characterized in terms the solvability Riccati inequalities. This done without restricting finite zero structure plant. If there are no system zeros on imaginary axis, /-problem can be treated a complete and satisfactory way. Explicit characterizations optimum to achieved provided, closed formula optimal value derived /-norm fixed transfer matrix. not attained, any sequence controllers bounded size which constructed approach infimal norm must necessarily high-gain. A globally quadratically convergent algorithm compute proposed. generalized problem measurement feedback. >
