直接转矩控制在交流传动中的应用

Applications of Direct Torque Control in AC Drives

直接转矩控制(DTC)由ABB研发广泛应用在不同领域。直接转矩所有的开关变换是基于电机的电磁状态。最优的转换是在每个以25μs为控制周期时间内的。直接转矩控制适用于所有类型的交流系统,即直接转矩控制对于不同的应用提供了一个通用的平台。

Direct Torque Control（DTC）is developed by ABB,and is widely applied in different fields.In DTC,all changes of switch are based directly on the electromagnetic state of motor,and the optimum switching is within every control cycle of 25 microseconds.DTC is applicable to all kinds of AC systems,which means that it provides a general platform for different applications.
