Abstract

This paper describes a set of automatic tuning schemes for speed sensorless vector controlled induction motors. The importance of a self-commissioning inverter for sensorless drive systems is highlighted and a new tuning method of parameters needed for a sensorless drive system is proposed and explained. The tuning includes the estimation of the induction motor parameters used to estimate the speed and to control the motor. The proposed method is compared to recursive least-squares estimation (RLSE) which is conventionally used to identify the parameters of the motor
