Abstract
A control scheme for direct torque and flux control of induction machines based on the stator flux field orientation method is proposed. With the proposed predictive control scheme, an inverter duty cycle is directly based on the torque and flux errors, the transient reactance of the machine, and an estimated value of the voltage behind the transient reactance. A method is presented by which a voltage space vector can be calculated in order to control the torque and flux directly in a deadbeat fashion. The inverter duty cycle can then be calculated using the space vector PWM technique. An alternative modulation scheme is also presentedKeywords
