Investigation of the transient behaviour of a current-fed autopiloted asynchronous induction machine

The transfer functions associated with an autopiloted current-fed asynchronous induction machine are determined. The parameters influencing the static and dynamic performance are presented. Subsequently, it is shown how these performances are modified by the conditions imposed at the inputs of the group. Finally, a speed regulation is investigated in the case where the machine is fed with the rotor-current frequency imposed. The results obtained theoretically, with the aid of this model, are confirmed by experimental results from a practical working system.
