摘要

One of the ways to control the dynamic of an induction motor is using Field Oriented Control (FOC) or Vector Control. But in this case we can remark electrical disturbance represented by coupling between direct and quadrature currents of induction motor and parameters uncertainties. This disturbance degradate the control law when the rotor speed grows. In this paper we proposed a algorithm to improve the performance of vector control. The algorithm is based on Lyapunov's Direct Method and it is used to estimate this disturbance and eliminated him. Simulation results are shown to validate the proposed technical.
