Abstract :
A novel DSP based control system of permanent magnet brushless in-wheel motors used for micro electric vehicles (EVs) is presented. A new digital electric differential algorithm and the corresponding control techniques, such as the measurement of the phase current by using one current sensor, the phase position measurement etc., are also discussed. Experimental results are presented to validate the feasibility and robustness of the proposed control system in engineering applications of EVs.
