Abstract

In this paper, a new H_∞ controller reduction method are proposed to preserve the H_∞ property using frequency-weightings. The weightings are obtained easily from the form of all controllers satisfying the H_∞ performance requirement. An illustrative example is presented to demonstrate the effectiveness of the proposed approach.
