Abstract

A sensorless induction motor drive with stator resistance online estimation is presented. The drive is particularly suitable for low speed operations. Resistance estimation is based on a two-time-scale approach, and the error between measured and observed current is used for parameter tuning. The simple full order observer used allows to keep direct field orientation in a wide range of operation. The system can drive active load and generate stall torque. The proposed drive has been simulated and then experimentally implemented, giving promising results
