摘　　要：在开关磁阻电动机系统中电流斩波控制和角位置控制是最常用的主要有两种控制方式。介绍了一种电流内环采用滞环控制的开关磁阻电动机控制方法。通过设定滞环环宽,将电机相电流控制在给定电流上、下一个环宽内,这样既可及时迅速地跟踪给定的电流,避免电机起动过程中的电流过大现象,又能快速地响应外环转速的变化,实现快速稳定的控制电机。内环采用新型的滞环电流控制后,简单有效地解决了传统控制策略中电流斩波动态响应慢、角位置控制复杂的弊端。There are two most common methods, current chopping control and angular position control in the switched reluctance motor control system. The control method of switched reluctance motor with a current hysteresis control was introduced. Compared with a given current, the motor phase current wias controlled within a certain ring width by setting the hysteresis loop width. It can quickly track the given current to avoid that electrical current during startup is too large, and can quickly respond to changes in the rotational speed of the outer ring to achieve fast and stable control of the motor. After using the new inner hysteresis current control, it is a simple and effective solution for problems of the traditional control strategy such as slow chopping current dynamic response and complicated angular position control drawbacks.
