In this paper, a new <i>H</i><sub>∞</sub> controller reduction method are proposed to preserve the <i>H</i><sub>∞</sub> property using frequency-weightings. It is necessary to consider decreasing degradation of <i>H</i><sub>∞</sub> property for <i>H</i><sub>∞</sub> controller reduction. It is well known that all <i>H</i><sub>∞</sub> controllers are represented by free parameters which are stable and bounded. In the paper, frequency-weightings are given to stabilize the free parameter, and low order controller is provided by using frequency-weighted balanced technique. Some numerical examples are illustrated to show effectiveness of our method.
