Parameter-Robust Sensorless Control of IPMSM Drives With Adaptive Flux Observer
This work addresses parameter sensitivity in sensorless control of Interior Permanent Magnet Synchronous Motors (IPMSM) by creating a robust framework. It uses an adaptive flux observer and a unified flux decomposition to separate errors: one component is compensated by tracking the total flux magnitude, while the other, caused by q-axis inductance mismatch, is identified using high-frequency voltage injection.
