  • Sensorless control of PMSM using measurement of phase voltages
    Urlep, Evgen ; Edelbaher, Gregor ; Jezernik, Karel
    The success of the speed sensorless control in low speed region depends greatly on the selection of the appropriate technique to obtain the unknown controlled variables. Both here presented, the ... control algorithm and the observer structure are based on the machine dynamics. Influence of the measured signal error and the parameter mismatch is described in the paper, where it is shown the significance of the applied approach. Another important issue is accuracy of the available measured signals and therefore special effort is required in that particular area. For that reason, besides measurement of the phase currents, the stator voltages are measured using branch voltage integration principle. Rather than using the reference value, the measured values of the phase voltages are used in observer, improving the performance of the system. Experimental results confirm the improvement gained by the described approach.
