| Abstract |
In this paper we have examined a permanent magnet sinusoidal synchronous servo machine with current controllers working in d-q (fixed to the rotor) reference frame. We used a simulation program, and examined the relations between the current range and the voltage demand. If the link voltage of the inverter is decreased, above a definite speed, in id and iq current components some oscillation will appear. The characteristics of this oscillation depend only on the parameter set of the servo drive, and the controllers. We gave a reasonable method for decreasing the “q” component of the current to avoid the oscillations in the currents. |
