Abstract: The present invention relates to a method and system for controlling a doubly-fed induction machine. In operation a rotor current vector is processed with a rotor position estimate vector. A scalar error quantity is the determined in dependence upon a stator current vector and the processed rotor current vector. The scalar error quantity is integrated and an estimate of the rotor angular frequency is determined in dependence upon the integrated scalar error quantity. To obtain a rotor position estimate, the estimate of the rotor angular frequency is integrated and a rotor position estimate vector is determined in dependence upon the rotor position estimate. The rotor position estimate vector is then provided for processing the rotor current vector. As output signals a signal indicative of the rotor position estimate vector and a signal indicative of the estimate of the rotor angular frequency are provided for controlling the doubly-fed induction machine.
