Abstract: The difference between conventional switched reluctance motor control strategy and novel bipolar excitation control strategy was studied. On the basis of the novel control strategy, using TMS320F28335 as the core, designed a switched reluctance motor speed control system with threephase fullbridge inverter, and used a low cost slot photoelectric switch sensor instead of photoelectric encoder as the position sensor to realize the change of the conduction angle control. A 3kW 12stator pole and 8rotor pole prototype motor which was used in electric vehicle was applied in the experiment, and the experiment results show that the designed system can well achieve the predetermined control target.
