Abstract: | This paper presents a T-S model-based fuzzy controller design approach for electromagnetic suspension systems. The T-S fuzzy model is firstly applied to represent the nonlinear electromagnetic suspension systems. Then, based on the obtained T-S fuzzy model, a fuzzy state feedback controller is used to ensure the required mixed ℓ2-ℓ∞ performance of original electromagnetic suspension system to be achieved. This controller is designed in a nonparallel-distributed compensation scheme. And sufficient conditions for the existence of such a controller are derived in terms of linear matrix inequalities. Finally, numerical simulation on an electromagnetic suspension system is performed to validate the effectiveness of the proposed approach. Copyright © 2013 Published by Elsevier Ltd.
