Citation: Tuovinen, Toni & Hinkkanen, Marko. 2014. Adaptive Full-Order Observer With High-Frequency Signal Injection for Synchronous Reluctance Motor Drives. IEEE Journal of Emerging and Selected Topics in Power Electronics. Volume 2, Issue 2. 9. ISSN 2168-6777 (electronic). DOI: 10.1109/jestpe.2013.2294359.
Abstract: A back electromotive force-based position observer for motion-sensorless synchronous reluctance motor (SyRM) drives is augmented with high-frequency signal-injection method for improved low-speed operation. Previously proposed observer structure is further improved to account for the cross saturation in the motor. The combined observer is experimentally evaluated using a 6.7-kW SyRM drive in low-speed operation and under various load conditions. The resulting position error at low speeds and standstill is small.
