摘要：

This paper presents a decoupled current control based on disturbance observer applied to sensorless induction machine drives. The algorithm for rotor speed estimation is obtained from the observed disturbances used in the current control loop. An adaptation law for the estimated rotor speed derived from the disturbance observer is proposed to feedback the rotor speed control loop. The stability analysis of the disturbance observer and the proposed rotor speed estimation technique is presented based on a Lyapunov approach. Experimental results are presented to validate the proposed technique.
