Conference Object Citation - WoS: 1Citation - Scopus: 1Sensorless Position and Speed Control of IPMSM With Sliding Mode Observer and Voltage Signal Injection(IEEE, 2021) Ates, Ertugrul; Tekgun, Burak; Ablay, GunyazA sensorless control approach based on a sliding mode observer for predicting the rotor position and speed is studied in this work. For predicting the motor speed and position, the sliding mode observer followed by a phase locked loop is formulated by means of the back EMF model. The voltage signal injection method is utilized for accurate estimation in zero or low speed region. Numerical simulation results are provided for an 8-pole IPMSM, which shows that the motor speed and position in zero or low-speed region are accurately estimated with the designed observer and voltage signal injection approach.Article Citation - WoS: 1Citation - Scopus: 1Design and Real-Time Implementation of a Sliding Mode Observer Utilizing Voltage Signal Injection and PLL for Sensorless Control of IPMSMs(Elsevier - Division Reed Elsevier India Pvt Ltd, 2024-11) Ates, Ertugrul; Tekgun, Burak; Ablay, Gunyaz; Barut, MuratIn this study, a sliding mode observer (SMO) based on high-frequency (HF) voltage signal injection and a phase-locked loop (PLL) is proposed for estimating the extended electromotive force (EEMF), rotor position, and rotor velocity of an interior permanent magnet synchronous machine (IPMSM). This approach addresses real-time estimation challenges associated with standard SMO and PLL at very low speeds and standstill. A reliable and accurate sensorless speed control system for IPMSM is then developed and implemented in real time using the proposed SMO and PLL, covering a wide range of speeds, including low-speed and standstill conditions. The SMO effectively estimates the EEMF, while the PLL extracts the rotor velocity and position based on these estimates. Compared to conventional SMO and PLL methods, real-time results from an 8-pole, 0.4 kW IPMSM demonstrate the superior efficiency of the proposed system.
