摘要：

We consider the problem of minimizing the H-2 norm of a feedback system subject to the constraint that the controller robustly regulate against constants and sinusoids. We show that, for any epsilon > 0, there exists a controller that both achieves robust regulation and renders the closed-loop H2 norm within epsilon of the optimal norm (the norm achievable without the robust regulation constraint). We also provide conditions that are both necessary and sufficient for there to exist a robustly regulating controller that achieves the optimal H2 norm. All proofs are constructive.
