Abstract

Robust Hinfin fuzzy controller is proposed in this paper to overcome the parametric uncertainties of fuzzy large scale systems (FLSS) and get Hinfin performance. In terms of Lyapunovpsilas second method and decentralized scheme, a stability criterion is derived via linear matrix inequalities (LMIs). Based on this criterion, a set of fuzzy parallel distributed compensation (PDC) controllers is synthesized, and adopted to stabilize the FLSS with parametric uncertainties. The effectiveness of the proposed approach is shown through a numerical example.
