Abstract :
In this paper a novel current control method of the switched reluctance motors (SRMs) is proposed, which has considered the mutual inductance with simultaneous two-phase excitation. Attention will be paid to the effect of mutual inductance upon winding current with simultaneous excitation of two phases. The off-line training of RBF network is based on the data acquired by experimental data. After trained, RBF could be able to achieve the nonlinear mapping between current, position and inductance. According to the tendency of current acquired by the RBF, the duty of PWM should be adjusted so as to obtain the optimized current control. The results of experiment proved that this method could make the actual current follow the given current.
