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)
As switched reluctance motors (SRM) generally offer a simple and robust design, they are very suitable for an aircraft main engine fuel pump drive which needs to be actuated by fault tolerant drives. Based on analytical comparison the merits and demerits of some different machine topologies including redundancies, a six phase 12/8 fault-tolerant SRM is(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)
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)
As solutions to the problem of flux-weakening in brushless DC (BLDC) motor, sophisticated control methods and high switching frequency in flux-switching permanent magnet motors, this paper presents a novel parallel permanent magnet flux-switching motor, which inherits the advantages of permanent magnet motor, e.g. high power and torque density, and good(More)
