    Abstract

    With the development of power electronics and motor control, AC motor speed control system or servo system has been widely explored. Among them, the induction motor driving based on three-phase six-switch inverter has become one of the hottest topics. However, in certain applications, people want to further strengthen the cost savings. At the same time, the driving system is desired to have the fault-tolerant ability. Under the circumstance, the motor operation mode based on the three-phase four-switch inverter came into being. However, it has fewer voltage vectors, with unequal amplitudes, spatial asymmetry, and no zero vector, which will inevitably lead to the deterioration of the dynamic and static performance. In this paper, the theory of four-switch motor operation mode and its control performance is deeply analyzed. The model predictive direct torque control algorithm is proposed in order to obtain better static and dynamic characteristics.
