ABSTRACT
Motion (position, speed, torque) control of electric motors and active and reactive power control in electric generators are the first means for increased productivity and energy savings in all industries with variable-in-time output. When torque fast response and control precision are required, the so-called field oriented control (FOC) and DTFC are preferred for a.c. motors/generators control. As expected, FOC and DTFC imply rather complex control.
