Method for determination of electromagnetic parameters of submersible induction motors

open access: yesOmsk Scientific Bulletin, 2019
Positive and energy saving frequency control of submersible asynchronous electric motors demands a research of its work as a part of electrotechnical complexes of installations of electrocentrifugal pumps on the basis of modeling. This approach is oriented to development of ways of identification of parameters of its equivalent circuits on experimental

Speed-Sensorless Control of Induction Machines with LC Filter for Geothermal Electric Submersible Pumping Systems

open access: yesMachines, 2022
A speed-sensorless state-feedback controller for induction machines (IMs) with LC filter is proposed. The speed and state estimation is based on a speed-adaptive observer, requiring only the measurement of the filter input currents.
