Induction motor control based on adaptive inverse control

In this paper, An improved adaptive inverse control strategy is presented for induction motors drive system. The reference signal and the disturbance signal are controlled, which can achieve optimal effect in the meantime. Applying adaptive LMS algorithm based on variable step and variable region to variable frequency speed regulation system, the initial convergence rate, tricking ability of time-varying system and stable precision are best. Computer simulation results and the outcomes of real-time experiment are included in the paper to show the effectiveness of the proposed method.
