The Linear parameter Varying and sliding mode observers are studied in this paper. Both the rotor resistance and speed variation are considered. The design of the considered observers is described in detail. In order to conduct a comparative study, the measurements used for both observers are assumed available on an equal basis. Equally, the same controllers parameters are used in simulation of a field oriented control scheme. In terms of variations of motor parameters, the estimations of observers are compared on a basis of errors estimation either during transient and steady state operations.
