【Abstract】 To overcome the highly nonlinear characteristic of the SRM,the on-line control strategies are presented to automatically adjust the excitation parameters,the strategies are as follows,the intelligent adjustment of the turn-on angle to maximize the ratio of the average torque to RMS phase current,turn-off compensation to reduce torque ripple;fuzzy logic control to give the reference current based on speed error and its change.The simulation results show the effectiveness of the system.更多还原
