Efficient Design for PMSM Control and Real-Time Diagnosis Based on FreeRTOS for e-Bike Application

This paper deals with the freeRTOS-based permanent magnets synchronous motor (PMSM) control algorithm developed by ST microelectronics and the optimal diagnostic tasks implementation in a freeRTOS-based e-bike control firmware. The purpose of this work is to investigate the STM32 freeRTOS-based firmware, to develop and implement optimally the diagnostic tasks of an e-bike PMSM. The implementation of the diagnostic tasks is achieved after a detailed and insightful analysis of the STM32 PMSM control firmware and realized through the utilization of a feature provided via freeRTOS which is: task notification and deferred interrupt handling.
