Parameters Tuning and Poles Designation for Sensorless Induction Motor Drive

Abstract:

This paper presents a completely analysis for the state observer whose state variables are stator currents and rotor fluxes and a new poles designation method is proposed and a detailed process of designing is also described.Then the adaption laws for stator resistant and rotor resistant and speed are given.The proposed method is verified with simulation and experiments.

Key words:stator observer; poles designation; stator resistance identification; rotor resistance identification; speed identification
