چکیده

In this study an improved direct torque control method (DTC) for Axial-flux hysteresis motor speed controlling is investigated. Time-consuming and dangerously of the necessity to manually adjust the motor speed and voltage when motor lagging occurs are the main drawback of the conventional control methods. The proposed method under acceleration and sequential braking on the Axial-flux hysteresis motor, based on the extracted modified motor dynamic equations in the Simulink Matlab environment has been simulated. As the results show, by using the proposed direct torque control method, the speed of the motor in the consecutive acceleration and braking process is controlled and the referral speed throughout the process operation with high accurate has been followed. Also this control system has shown that it is reliable method and stable against disturbances. Compared with conventional vector control methods, less complexity, higher speed and accuracy and easier implementation ability are significant features of the proposed method.
