| Abstract: | The control strategy of asynchronous motor based on cascaded multilevel inverter is mainly introduced. First, the inverter's topology and basic principles are described as well as the method based on carrier phase-shifted SPWM. Then the VVVF which employed widely to control asynchronous motor is introduced. The performance of the method is examined by simulations and experiments. At the end, vector control and speed sensorless vector control principle based on MRAS emphatcully are emphatically described. Th... |
