The analysis and implementation of the various control possibilities of electric motors are among the frequent research and development tasks that a development engineer could face these days in automotive-related projects. These motors are applied in more and more areas in the vehicles, thus their efficiency is a key factor in terms of both their mechanical and control structure.
The permanent-magnet synchronous motor is especially popular in modern-day automotive applications because of its numerous advantages from which its performance, efficiency and robustness shall be emphasized. However, to drive this type of motors, it is essential to use an electronic control unit based on a microcontroller.
My thesis work’s aim has been to design and implement the control system of such a three-phase permanent-magnet synchronous motor using a high-performance, multi-core microcontroller, a member of the Infineon AURIX™ TriCore™ TC2XX automotive processor family. This way, it has been my task to create a development platform that can be expediently used by colleagues working on pre-development projects involving electrical motor control. My work has taken place at the research and development institute of Knorr-Bremse Systems for Commercial Vehicles, Budapest.
