A novel high performance torque control scheme for switched reluctance motors(SRMs) is proposed based on online fuzzy neural network modeling and adaptive sliding-mode current control. Firstly, an adaptive neural fuzzy inference system(ANFIS) is designed to learn the nonlinear static position-torque-current characteristic and the flux-linkage characteristic(More)
High torque density, wide speed range are required in electric motors used in electric vehicles. Based on the comparison of flux-weakening capability of alternate and all poles wound machines, this paper employs twisted-rotor structure and chooses the optimal twist angle to improve the symmetry of flux-linkage of alternate poles wound FSPM machine without(More)
This paper presents a five-degrees-of-freedom (DOF) magnetic levitation motor system. The rotor of the system is rotated by a high speed induction motor. In order to improve the integration level, reduce the volume and power loss of the system, one hybrid axial-radial magnetic bearing and one hybrid radial magnetic bearing are applied to suspend the rotor.(More)
Open-winding permanent magnet (PM) generator power system is an important research direction of wind power. Compared with rotor-PM motor, flux-switching permanent magnet (FSPM) machines have the advantage that is suitable for flux-weakening operation and has no risk of PM demagnetization. Hence, FSPM machine is applied to the open-winding power system in(More)
