    The efficient and fast control of electric power forms part of the key technologies of modern automated production. It is performed using electronic power converters. The converters transfer energy from a source to a controlled process in a quantized fashion, using semiconductor switches which are turned on and off at fast repetition rates. The algorithms which generate the switching functions-pul... View full abstract»

    Motion control techniques have been developed to exploit the high efficiency and extremely fast dynamic response capabilities of permanent-magnet AC (PMAC) machines. Control techniques are reviewed separately for the two major classes of PMAC machines referred to as trapezoidal (i.e., brushless DC) and sinusoidal machines. While trapezoidal PMAC machine drives are distinguished by their controls s... View full abstract»

    The author deals with the present status and future perspective of power electronics and motion control. This discussion is particularly relevant today because some electrical engineers believe that motion control is a part of power electronics. However, one belief is that power electronics and motion control are now distinct fields-despite having common technologies and shared roots View full abstract»
