D-Q control system and method for controlling a switched reluctance motor

A converter module for a D-Q control system to control a switched reluctance motor (SRM) by a torque command signal and a phase advancing signal in a D-Q domain, wherein the torque command signal and the phase advancing signal are each converted into a plurality of 3-phase control signals by a D-Q to ABC converter module, such that at least one signal component of one or more of said 3-phase control signals has a negative torque value, the converter module comprising:

• a negativity removal module to process the plurality of control signals, so as to distribute the negative torque value to one or more other control signals that do not have a negative torque value;
• and
• a non-linear module adapted to be coupled to the SRM, wherein said non-linear module removes distortion from each one of said control signals that has been processed by said negativity removal module, which are applied to the SRM to control the torque output therefrom;
• and
• a phase advancing module coupled to the DQ-to-ABC converter module, said phase advancing module configured to receive speed data of a rotating rotor of the SRM, such that said phase advancing module advances the phase advancing signal by an amount, wherein said amount of phase advancement is based on a comparison of an actual current being applied to the SRM to a threshold current value, so as to control the SRM, when the rotor of the SRM has moved to a predetermined position.
