Study on braking control system of switched reluctance motor

For the sake of extending the application of switched reluctance motor, a switched reluctance motor braking control system with four phase 8/6 structure is designed. This system is based on DSP56F803. Angular position control with fixed turn-off angle and unfixed turn-on angle combined with Pulse-Width Modulation and voltage-chopping control is used in this system. Finally, the results and waves of experiment are given. The result of the experiments indicates that the structure of the control system is simple and the system is feasible and has favorable performance.
