Abstract :
Based on Matlab/Simulink, Vector Control VWF System with Speed and flux feedback is proposed for asynchronous motor. It consists of asynchronous motor and current delay-loop PWM inverter, including speed regulator (ASR), flux observer and flux calculator etc. Furthermore, the design and parameters regulation for speed regulator (ASR) is realized by means of engineering design method of DC speed control system. At same time adapted flux feedback, the dynamic characteristics for Vector-control VWF System is improved. Simulation results show the system has batter dynamic and static performances.
