Marcus Hedegärd

Marcus Hedegärd is a PhD student in the Automatic control research group, where he investigates the benefits of, and develops potential usages for, a magnetoelastic torque sensor, when placed between the clutch and the gearbox in Volvo’s heavy duty vehicles. The improved knowledge of the actual torque can be used for reducing the load during gearshifts. Due to the hysteretic characteristic of the sensor, his introductory research involves hysteresis modeling and compensation which can improve the accuracy of the sensor. As a next step, Marcus will explore how to use the sensor as an additional measurement for motor diagnosis.
