Observer Assisted Current Reconstruction Method with Single DC-Link Current Sensor for Sensorless Control of Interior Permanent Magnet Synchronous Machines
Abstract
The paper presents an observer assisted current reconstruction based method to estimate the three phase currents by utilizing only one dc-link current sensor to realize position sensorless control of interior permanent magnet synchronous machine (IPMSM). The current reconstruction technique needs dc-link current information for at least two vector transition regions in a switching period to estimate the three phase currents. However, it is …
