On standard H/sub /spl infin// control of processes with a single delay

摘要: This note presents a frequency domain method to solve the standard H/sub /spl infin// control problem for processes with single delay. For given bound on closed-loop norm, there exist proper stabilizing controllers that achieve this if and only both corresponding delay-free an extended Nehari delay (or one-block problem) are all solvable. The solvability of is equivalent nonsingularity delay-dependent matrix. conditions formulated in terms existence solutions two delay-independent algebraic Riccati equations property. All suboptimal solving three problems are, respectively, parameterized as structure incorporating modified Smith predictor.
