This paper presented a novel speed sensorless vector control system of induction motor using the active disturbance rejection controller (ADRC) with a flux observer. The controller is not overly dependent on the accurate mathematical model of motor, so the system is inherently robust, and it can estimate and compensate the general disturbance that includes the unknown internal dynamics and the external...
It is difficult to develop an accurate mathematical model for the induction motor and the robustness of vector control system is poor. This paper proposes a new-type structure controller that adopts three first-order active disturbance rejection controllers (ADRC) and a proportional-integral (PI) regulator. The controller is not overly dependent on the accurate mathematical model of motor, so it can...
