Hardware-in-the-loop for on-line identification of SSP driving motor

Abstract

This paper describes a strategy for identification of Siemens-Schottel- Propulsor (SSP) driving motor which is chosen as three-phase squirrel cage induction motor (IM) in this work. The strategy is to perform on-line identification of parameters of the electrical part of IMs. The different forms of voltage and current signals are applied to the motor based on Siemens Sinamics technology, at the same time, detecting the motor voltage, current response signal, through all these signals and the relationship among them, the motor parameters can be calculated or the motor parameters can be identified using the fitting algorithm. Simulation and experimental results show advantages of the proposed strategy in the identified system, simplicity, and low cost. © 2012 Springer Science+Business Media, LLC.
