Electric drive platform: Speed control Implementation of low-level drivers


D. Srikantharupan

Semester Thesis, SS16 (10533)

Nowadays electric drives are used in many applications, ranging from small cooling fans to electric trucks. In consideration of this scale, the control of power electronics system (CPES) group of the automatic control laboratory at ETH Zurich is developing an embedded platform, where novel identification, estimation and control algorithm can be implemented and tested. In order to apply these methods, precise measurements with small errors and good data management are essential. For a fast control an ARM based control unit is used, therefore all real-time functions have to be optimized to deal with the computation time. To overcome these issues, measurement acquisition, PCB board design, logging and calibration have been developed in previous projects. In this project outcomes of those project were integrated and extended. In particular, for the startup and the calibration of the sensor an open-loop control algorithm was implemented. Therefore a mathematical optimized rotating frame was developed together with auxiliary functions. Finally, they were analyzed to get the best performance.
