Abstract
In this paper, we examine the usefulness of super-optimal H ∞ design in robust control. It is argued that the approach can lead to a more robust design than standard H ∞ control, but that there is usually a cost to pay in complexity of controller.
We outline a recently developed state-space approach for solving 2-block problems, which enables realistic designs such as mixed sensitivity to be solved. This is then used to design the super-optimal controller for a simple example and the results are compared with those of a standard H ∞ controller.
