采用矢量控制方式的通用变频器不仅可在调速范围上与直流电动机相匹配，而且可以控制异步电动机产生的转矩。由于矢量控制方式所依据的是准确的被控异步电动机的参数，有的通用变频器在使用时需要准确地输入异步电动机的参数，有的通用变频器需要使用速度传感器和编码器，并需使用厂商指定的变频器专用电动机进行控制，否则难以达到理想的控制效果。目前新型矢量控制通用变频器中已经具备异步电动机参数自动辨识、自适应功能，带有这种功能的通用变频器在驱动异步电动机进行正常运转之前可以自动地对异步电动机的参数进行辨识，并根据辨识结果调整控制算法中的有关参数，从而对普通的异步电动机进行有效的矢量控制。除了上述的无传感器矢量控制和转矩矢量控制等，可提高异步电动机转矩控制性能的技术外，目前的新技术还包括异步电动机控制常数的调节及与机械系统匹配的适应性控制等，以提高异步电动机应用性能的技术。为了防止异步电动机转速偏差以及在低速区域获得较理想的平滑转速，应用大规模集成电路并采用专用数字式自动电压调整（AVR）控制技术的控制方式，已实用化并取得良好的效果。
