Abstract

Direct torque control (DTC) method with correction of stator flux vector is presented in the paper. The correction is made by means of appropriate component of stator current vector. Thus, controlled quantities (electromagnetic torque and stator flux) are estimated only from stator parameters and measured stator quantities, and there is no need to use rotor parameters, which are dependent on the operating condition, and rotor quantities, which cannot be measured. With the proposed method stable operation in whole speed range, robust start-up with slow change of the torque and fast torque response are achieved. Simulations and experimental tests verify the validity of the method.
