Abstract：Existing disturbances in the direct torque control of induction motor drive system, we proposes a composite control scheme based on extended state observer (ESO) and the continuous finite time control (FTC) to improve the dis-turbance rejection property of the system;the estimated value is used in the feedforward compensation design. Secondly, a continuous feedback-based finite-time control technique is applied to the feedback design. Then, the stability of the con-troller is analyzed. Simulation and experimental comparisons with other two methods, traditional PI and P+ESO, are given to validate the effectiveness of the proposed method.
