T-S fuzzy control of IPMSM using backstepping integral sliding mode

This paper aims to design a robust controller for the Interior Permanent Magnet Synchronous Motor (IPMSM) based on the Takagi-Sugeno (T-S) fuzzy modeling, the sliding mode control(SMC) and the back-stepping control. The introduction of T-S fuzzy model is for the clearer description of nonlinear uncertainties and reduces computational burden, and the back-stepping technique for the considering of the load disturbance under the inevitable matching condition in the SMC. The Integral SMC is used for the problem of reaching phase.
