This paper elaborates the use of instantaneous voltage control method for control of torque in a five phase induction motor drive. In this method, instantaneous time modulating signals are generated, without the feedback of position of rotor, which enhances its easier implementation. These modulating signals being compared with triangular waves gives the required switching states input to the inverter...
In this paper, a new predictive direct torque control (DTC) method is proposed, improving the dynamic response of the classical DTC and reducing the torque- and flux-ripples through a voltage vector with an optimal phase. In the transient state, the voltage vector phase is selected in a manner where the fastest dynamic response is achieved, while in the steady state, this phase is selected in a manner...
