| Summary: | 碩士 === 國立雲林科技大學 === 電機工程系碩士班 === 94 === In this thesis, a fuzzy controller with highly dynamic torque regulation and efficiency optimization of the synchronous reluctance motor (SRM) using input–output feedback linearization is proposed. The cross-coupling effects in the SRM model and the torque nonlinearity due to the iron losses in torque–speed characteristics of the SRM are discussed. The criterion of the efficiency optimization is also introduced and investigated. We select the product of d- and q-axes torque currents as one of the output variables, the nonlinear and cross-coupling aspects between the d-and q-axes torque currents and the terminal currents can be eliminated. Hence, the linear torque–speed characteristic can be achieved. We use the fuzzy controller such that the transient performance is better than the PI controller.
