But in braking control strategy and the braking reliability
research is relatively less, the papers [1-3] of the switched
reluctance motor regenerative braking state of current,
torque and energy conversion were analysed. Based on
the opening of the SRM angle, turn off angle and other
parameters to optimize and control, but did not consider
the high speed operation, renewable energy feedback of
bus voltage pump up and over current influence and
suppression methods. the literature [4] the zero voltage to
maintain the opening of the third step braking control
strategy, opening, zero voltage keep open and full voltage
shut down of three step mode with full voltage, at high
speed braking performance than full voltage shut off
decreased slightly, but significantly reduces the bus
voltage pumping voltage and current. At low speed, the
brake torque can not be generated.
