摘要
针对开关磁阻电动机启动过程容易产生制动转矩使转速下降的问题,介绍了开关磁阻电机启动过程工作原理,分析了开通角和关断角对启动转矩的影响,提出了一种电流双闭环的启动转矩控制策略,建立了基于Matlab/Simulink的开关磁阻电动机启动系统仿真模型,与传统的电流单闭环控制策略相比,该方法能有效减小启动过程的制动转矩,使转速平稳上升。
For the problem of the starting process of switched reluctance motor generate the braking torque and make the speed down easily, the starting process principle of switched reluctance motor was introduced, the effect of the turn-on angle and the turn-off angle to the starting torque was analyzed, a starting torque control method based on the current doubled closed loop was proposed, the simulation model of switched reluctance braking system based on the Matlab/Simulink was established, compared with the traditional current single closed loop method, the proposed control strategy can reduce the braking torque effectively and make the speed rise clamed.
