In this paper, the theory of speed and discrete vector of flux closed-loop discrete principle is used to control Asynchronous Machine. According to PI regulating, PWM produces a feedback control signal, which is send to the pulse generator. And Variable frequency control is achieved by inverter. By using direct vector control system model with rotor speed and flux closed-loop, the simulation results show that the validity and reliability of parameters regulating, speed regulating performance and dynamic performance are all enhanced.
