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...
This paper presents a direct torque control (DTC) applied to a three-phase asynchronous motor supplied by three-phase rectifier with absorption of the sinusoidal current cascaded with a two levels inverter in order to improve certain electrical sizes as the source current, and other mechanical characteristics as the undulations of the torque and the flux's distortion. The speed control is realised...
