Abstract:

Purpose - This paper aims to present an observer application for a squirrel cage induction motor, which is a complex non-linear system with parameter variations. Design/methodology/approach - Proposes a non-linear observer with a great profit to follow up in real time the flux and rotor resistance of a squirrel cage induction motor. Findings - The robustness of induction motors encourages their use in the industry. But, to assure a reliable working and to detect probable breakdowns, it is necessary to control some important parameters in real time. The Park model of induction motors is non-linear. The results of the different simulations are presented in order to evaluate the performance of the proposed method. Originality/value - Provides information on an effective industrial application.
