Abstract

This paper focuses on the speed regulation of permanent magic linear synchronous motor (PMLSM) and proposes a guaranteed cost speed controller based on T-S fuzzy model theory. After translating current, voltage and speed variable to zero, T-S fuzzy model of PMLSM is established by the idea of piece-wise linearization and Ȇ-type membership functions. Feedback gain matrices can be getting by solving certain LMIs, which belongs to linear programming. Simulations show the validity of proposed method.
