摘要
根据开关磁阻起动/发电系统的特点,对其起动特性进行了分析,主要对起动转矩最大和起动转矩脉动最小两种情况进行了研究。在建立开关磁阻起动/发电系统仿真模型的基础上,对两种起动要求下主开关的开通角和关断角进行了不同转速下的仿真优化。然后对由静止到运动时的起动PWM占空比进行模糊算法估测,对两种起动要求下的不同控制算法分别进行了滑模+PI控制策略的设计。最后,利用开关磁阻起动/发电系统样机平台,验证了所设计起动控制方法的正确性。
According to the characteristics of switched reluctance starter/generator system, its starting performance has been studied under the maximum starting torque and the minimum starting torque ripple. After the simulation model of the switched reluctance starter/generator system is established, the turn-on angle and turn-off angle of main switch on the basis of the two control requirements is optimized at different rotor speeds. Then the fuzzy estimation of the standing PWM duty and the sliding ＋ PI control strategy of the two different starting requirements have been designed. Finally, using the prototype platform of switched reluctance starter/generator system, the starting control method is verified.
