On chaotification of a class of stable PMSM systems via T-S fuzzy state feedback control method

Abstract

In this paper, the problem of anticontrol of chaos for a class of stable permanent magnet synchronous motor systems is investigated. The Chen chaotic system is employed to be a reference system. The T-S fuzzy models of the stable permanent magnet synchronous motor system and the Chen chaotic system are introduced firstly. Then, based on the constructed T-S fuzzy models, a fuzzy state feedback controller is imposed on the stable permanent magnet synchronous motor system to track the reference system asymptotically. When the asymptotic tracking is reached, the chaotification of the stable permanent magnet synchronous motor system will be realized.Index Terms-PMSM system, non-smooth-air-gap, chaotifica tion, Chen chaotic system, T-S fuzzy model.978-1-4244-8035-7/10/$26.00
