Abstract: This paper describes the further development concerning an adaptive sliding-mode speed observer employed as the rotor speed and resistance estimators for a three-phase squirrel-cage induction motor (IM). The novel observer is improved from the previous work by a way of on-line calculating the errors of rotor flux estimations and then feeding them to the PI adaptive laws. For that reason, these errors vanish in steady state. Moreover, stability of the proposed observer is guaranteed and verified via the Lyapunov function and its derivative. Finally, the performance between the novel and the previous observers is compared fairly.
