Double switched reluctance motors parallel drive based on dual 89C52 single chip microprocessors

The developed double Switched Reluctance motors parallel drive is presented, which is made up of two four-phase 8/6 structure Switched Reluctance motors, two four-phase asymmetric bridge power converters and the controller. The four-phase 8/6 structure Switched Reluctance motor, the four-phase asymmetric bridge power converter and the control scheme are described. The closed-loop rotor speed control of the main motor and the closed-loop rotor speed control of the subroutine motor could be based on the pulse width modulation fuzzy logic algorithm, which is implemented by dual 89C52 single chip microprocessor controller. The experimental results of rotor speeds and phase currents in two Switched Reluctance motors are given.
