摘　　要：研究了一种新型开关磁阻电机双向控制系统,介绍了开关磁阻电机的发电/电动工作原理。基于电动汽车的运行特点,分析了其数学模型,并确定控制策略,采用H桥式功率主电路,运用电流和电压两种斩波控制方法。最后对样机进行实验研究,在电动和发电两种状态下,系统运行稳定、性能良好,从理论和实践上为电动汽车的制动能量的回收提供了可行性方案。This paper studies about a new control system designed for a switched reluctance motor（SRM）,and then the work principle of SRM is classified as a generator and electric motor.Based on the operating characteristics electric vehicle and the analysis of mathematical model of SRM,the control strategy is defined and H-bridge converter for SRM is built,using chopped current control and voltage chopping control as the major control chip.Finally,the experiments have been done on this SRM bidirectional control prototype system,and based on the experiments under the state of generating and electric motor.The result shows that the prototype system has stable operation and good properties,and the practical exploration is provided for braking energy recovery of electric vehicles both in theory and practice.
