Real Time Implementation of the PMSM Sensorless Control Based on FOC Strategy

This article presents the development stages of the real-time implementation for a Permanent Magnet Synchronous Motor (PMSM) control system. The control structures specific to the Field Oriented Control (FOC) strategy, the hardware elements, and the software programming environments used are presented. These stages can be presented in a chained manner in the form of stages such as: Model-In-the-Loop (MIL), Software-In-the-Loop (SIL), Processor-In-the-Loop (PIL), and Hardware-In-the-Loop (HIL). Moreover, in addition to the presentation of these stages, the article also presents the identification and tuning stages inherent to any control system. The results obtained in each of these stages are presented, the final goal being the study of the evolution in real-time of the performance of the PMSM control system.
