Considering the output voltage of switched reluctance generator, an angle control strategy using adaptive genetic algorithm is proposed based on the analysis on the characteristics of angle control and the influencing factors of output voltage ripple under high speed condition. When the speed or load changes, turn-off angle remains unchanged, and conduction angle is adjusted through adaptive algorithm to stabilize the voltage quickly. The genetic algorithm is applied to optimize the combination of opening angle and turn-off angle for the purpose of reducing the voltage ripple. Simulation and experimental results show that compared with single adaptive control or genetic algorithm angle control, the proposed strategy can optimize the output voltage quickly and accurately.
