Abstract:

The problem for the fluctuation of the output voltage during commutation of the switched reluctance generator (SRG)was discussed, Aiming at the reason,the principle of generator was analyzed. The current distribution method was used to allocate the specified current to each phase winding and the current in the commutation interval compensated each other and reduced current fluctuation. And the current control strategy based on fuzzy iterative control algorithm was introduced and can further improve the current convergence speed and tracking accuracy and while reduce the output voltage steady-state error compared to the iterative current control,thereby achieve the output voltage optimization.Simulation analysis and prototype test show that the control strategy can effectively suppress the output voltage fluctuation and reduce steady state error.

Key words: switched reluctance generator (SRG), voltage fluctuation, current distribution, iterative learning control (ILC), fuzzy iterative control
