Speed estimation is the most important issue in sensorless drives for induction motors. Estimation generally is based on the currents and voltages measurements; therefore, the correct speed estimation could be wrong due to deficiencies in the voltages and currents acquisition. This paper presents the effects in the speed estimation caused by the erroneous(More)
In this paper, the speed observer design problem for induction motors is approached by means of an estimation technique which exploits some properties of the error dynamics that make feasible to express this system as a feedback interconnection, subject to a disturbance signal, of two subsystems that can be rendered passive via a proper choice of the output(More)
