摘要： In some embodiments, a system of controlling an induction electric motor, includes a command voltage output unit for generating a command voltage for operating an inverter according to a command speed and outputting the generated command voltage to the inverter; a control unit for controlling the command voltage output unit such that the command voltage output to the inverter is compared with an operation limiting voltage and the command voltage is corrected to fall within the operation limiting voltage; and the inverter for controlling the induction electric motor depending on the corrected command voltage. Thus, it is possible to precisely control the induction electric motor even in a high speed operation region by regulating the magnitude of the command voltage applied to the induction electric motor by means of dynamic modulation strategies without the magnetic flux controller.

摘要翻译：在一些实施例中，控制感应电动机的系统包括：指令电压输出单元，用于根据指令速度产生用于操作逆变器的指令电压，并将产生的指令电压输出到逆变器; 控制单元，用于控制指令电压输出单元，使得输出到逆变器的指令电压与操作限制电压相比较，并且将指令电压校正为落在操作限制电压内; 以及用于根据校正的指令电压来控制感应电动机的逆变器。因此，通过在没有磁通量控制器的情况下通过动态调制策略来调节施加到感应电动机的指令电压的大小，即使在高速操作区域也可以精确地控制感应电动机。
