摘要：
In order to realize high power and reliability of speed control system, fault-tolerant induction motor control system based on three-level inverter is studied in this paper. Based on three-level inverter, a fault-tolerant inverter topology with an extra leg providing the current path during the post-fault operation is proposed. A corresponding control strategy is investigated to avoid voltage drift of the dc link midpoint. In this paper, an induction motor direct slip linear control (DSLC) is employed and investigated to reduce torque ripple and flux magnitude deviation in three-level system. Both simulation and experimental system have been set up to verify the effectiveness of the proposed control strategy.
