Abstract  

Variable voltage variable frequency (VVVF) speed control strategies were researched based on the mathematical model of alternating current (AC) asynchronous motor in order to achieve more accurate speed control of AC induction motor. The early control methods of induction motor based on the steady-state model were simply summarized. Three mature control schemes based on the dynamic model were introduced. The application of modern control theory in AC asynchronous motor speed control system was analyzed. Finally, the future development direction of AC speed control strategy was given. Traditional strategies were  maturely utilized in industrial field, but the modern control theory and advanced control algorithms still have vast potential for future development.
