To improve asynchronous motor control performance, space vector PWM technology is adopted according to the principle of asynchronous motor vector control, in accordance with the asynchronous motor stator circular rotating magnetic field generated tracking the control of inverter switching movements, supply ideal sinusoidal motor current, improving asynchronous motor steady, dynamic performance. Combining the virtues of high speed digital signal processor TMS320LF2407A computing speed,high precision, real - time control algorithms SVPWM, establishes the asynchronous motor rotor magnetic field oriented vector control system. The experimental results show that the system programme is feasible and has a good work performance.
