Designing driving and control circuits of four-phase variable reluctance stepper motor using fuzzy logic control

Autor: Auday Al-Mayyahi, Rabee' H. Thejel, Ramzy S. Ali

Precise positioning and repeatability of movement for stepper motors require designing a robust control system. To achieve that, an analytical model of a four-phase variable reluctance stepper motor is presented. A proposed open-loop driving circuit
