基于自抗扰观测器的感应电机速度估计方法

A speed estimation method for induction motors (IMs) based on active disturbance rejection observer (ADRO) is proposed in this article, in order to realize the sensor-less control of IMs. Benefit from the antidisturbance mechanism of ADRO, the exogenous disturbance can be estimated instantaneously, so that ADRO can realize the disturbance estimation accurately without the knowledge of the exact sy...
