Research On Fuzzy Optimization Of H∞ Control Based On Mixed Sensitivity Function

In this thesis, A design method of H( parameter fuzzy optimization is introduced, which is combined with the selection of mixed sensitivity weighting functions. This presentation is limited to single-input-single-output linear feedback control system. To the question of H( controller's conservatism, this paper presents a method to improve dynamic performance of the control system. In this paper the relation between robust performance and weighting functions is also discussed. Farther the fuzzy optimization is considered. The goal is to obtain both robustness and dynamic performance.Experiment results show that the controllers designed in this paper have the virtues of good realization, strong robustness and good dynamic performance, also have good performance under both structured uncertainty and unstructured uncertainty.JinHongLiang(Control theory and Control engineering)Directed by Prof.LiuJiZhen LiDaZhong...
