  • D-Q control system and method for controlling a switched reluctance motor
    Patent number: 9608554
    Abstract: A D-Q or rotating reference frame control system for a switched reluctance motor (SRM) provides a negativity removal module and a non-linear model module. As such, the control system utilizes control inputs fq and fd, which are converted into the ABC domain as electrical current functions f?ix with negative values. The negativity removal module is configured to share the torque portion of the negative values of the electrical current functions f?ix for each of the three phases of the SRM motor to remove the negative values. The non-linear module corrects the non-linearity of the SRM to smooth the torque that is output. The control system also utilizes a phase advancing module, which outputs fd for achieving a wide range of operating speeds.
