Abstract

The design of two interconnected observers for induction motor drive in sensorless application is adressed in this paper. The first one is dedicated to angular speed and load torque estimation while the second estimates fluxes. Stability of both observers is discussed. Moreover due to the complexity of observation at low frequencies, a part of the contribution of this paper is that the observers are tested and validated on reference trajectories of a sensorless induction motor observer benchmark. This benchmark is applied on an experimental set-up located at IRCCyN (Nantes, France). Robustness experiment tests with respect to parameters variation emphasize the applicability of the designed observers
