摘要: The direct torque control of induction motor has good dynamic performance and flux. However, the switching frequency is variable difficult to due use hysteresis controllers. That origin flux ripples. And a two levels voltage inverter limits drive system power. To overcome these problems, we propose study in this paper modified DTC approach by using three-level (NPC structure) instead two-level inverter, controllers are replaced one fuzzy controller finally PI speed used classical controller. All changes designed not only minimize ripples but also increase power range provide an intelligence control.
