This study presents an adaptive vector control method for reducing the inductance sensitivity of synchronous reluctance machine drives. In the proposed control structure, the direct and quadrature inductances are identified online by using an extended Kalman filter. Therefore, only the stator resistance of the machine parameters needs to be pre-identified during the installation process. Since variations in inductances can be tracked by the estimator, the proposed adaptive vector control is able to outperform the conventional field-oriented control in cases of inductance uncertainties, as shown by the simulation results.
