等效成两相静止坐标系下的交流电流Ia1Ib1，再通过按转子磁场定向旋转变换，等效成同步旋转坐标系下的直流电流ImIt1(Im1相当于直流电动机的励磁电流；It1相当于与转矩成正比的电枢电流)，然后模仿直流电动机的控制方法，求得直流电动机的控制量，经过相应的坐标反变换，实现对异步电动机的控制。其实质是将交流电动机等效为直流电动机，分别对速度，磁场两个分量进行独立控制。通过控制转子磁链，然后分解定子电流而获得转矩和磁场两个分量，经坐标变换，实现正交或解耦控制。矢量控制方法的提出具有划时代的意义。然而在实际应用中，由于转子磁链难以准确观测，系统特性受电动机参数的影响较大，且在等效直流电动机控制过程中所用矢量旋转变换较复杂。

传递触发信号，一般采用光纤传输，能有效地避免各种电磁干扰。通过光纤传递信号，也有两种方式：一种多光纤方式，一种单光纤方式。多光纤方式即每块触发板有一路光纤；单光纤方式即每一相只有一路光纤，信号传递到一块主触发板，再由主触发板传递到同一相的其他触发板。由于各路光纤光电传输过程中损耗不尽一致，因此从触发一致性上看，单光纤的方式比多光纤可靠。高压软启动器对信号的检测比低压软启动器要求更高。高压软起动器所在的环境存在着大量的电磁干扰，并且高压软启动器所用的真空接触器和真空断路器在其分断和闭合过程中会产生大量的电磁干扰。所以对检测到的信号不仅要进行硬件滤波，也要进行软件滤波，去掉干扰信号。软启动器在完成启动过程后。

要切换到旁路运行状态，如何平滑地切换到运行状态，这也是软启动器的一个难点，如何选准旁路点非常重要。旁路点早了，电流冲击非常大，即使在低压条件下，也会造成三相电源中断路器跳闸，甚至会损坏断路器。高压条件下危害更大。旁路点迟了，电机抖动得厉害，影响负载正常工作。因此，旁路信号的硬件检测电路必须非常，并且程序处理也要恰到好处。维修检查编辑平时注意检查软起动器的环境条件，防止在超过其允许的环境条件下运行。注意检查软起动器周围是否有妨碍其通风散热的物体，确保软起动器四周有足够的空间（大于150mm）。定期检查配电线端子是否松动，柜内元器件有否过热、变色、焦臭味等异常现象。定期清扫灰尘，以免影响散热，防止晶闸管因温升过高而损坏。
