Mixed H∞ optimisation with model-matching

This paper describes a class of the mixed H/sub infinity / optimisation with model-matching problems. The sensitivity and stability margin objectives are integrated in the model-matching design, respectively. Both approaches give a means of directly accessing the sensitivity/robustness objectives through a trade-off on the perfect model-matching objective. These applications to the known H/sub infinity / theory thus deal with important objectives such as multivariable interaction, which cannot be easily captured in the existing mixed sensitivity design. >
