Abstract

Owing to the benefits of uncomplicated design, compact dimensions, and superior power density, interior permanent magnet synchronous motors (IPMSMs) have garnered the attention of numerous researchers, both nationally and internationally. Nevertheless, conventional IPMSM models incorporating sensors, encoders, and additional apparatus often incur substantial equipment expenses and heavily depend on sensor accuracy for effective control. Consequently, the pursuit of sensorless control has emerged as a prominent trend in the domain of IPMSM control. In this work, a new sensorless control based on an integral synergetic observer (ISO) for an IPMSM is presented. The suggested observer has been developed to overcome the challenges posed by conventional observers, such as fragility against various disturbances, and establishing a sensorless control scheme capable of easily integrating into a modern application like electric vehicles. A comparison through numerical simulation tests using MATLAB software, between the proposed observer and the classic Luenberger observer (LO) clearly showed its qualities and its great importance. Notably, the ISO achieves improved performance metrics, such as the integral absolute error (IAE), integral square error (ISE), and integral time absolute error (ITAE). In low-speed control tests, the proposed ISO reduced the IAE by 56.90%, the ITAE by 55.83%, and the ISE by 75.82% compared to the LO.
