| Abstract |
The steady state torque capability of induction machines in a very wide field weakening region is discussed. Since the machines behaviour is independent of the chosen reference frame, the optimal torque can be achieved with rotor flux oriented control schemes as well as with stator flux oriented control schemes. On the other hand, these two basic control concepts can differ with regard to the dynamic behaviour and the measures that are necessary to achieve the optimum. These effects are compared for a well known rotor flux oriented control with inner current control loop and the stator flux oriented Indirect Torque Control. Furthermore, an extension of the Indirect Torque Control is presented that provides comparable conditions to the rotor flux oriented control in a very wide field weakening region. |
