Dynamic operation of FOC induction machines under current and voltage constraints

摘要

This paper analyzes the dynamic performance of FOC induction machines operating under current and voltage constraints. FOC rely on the proper performance of the inner current control loops. The capability of the machine to increase its torque can be seriously compromised due to the inverter voltage and current limits, which affect to the current regulator transient response. This can be especially critical in machines controlled to operate with reduced rotor flux to increase their efficiency.
