The identification results are validated a simulation by Simulink/ MATLAB. After, we have studied the direct and indirect vector control of asynchronous machine fed by voltage inverter controlled by PWM. A robust test of the control with optimized flux is made. This test showed that the vector control is sensitive to parameters variation in any level flux.
