Abstract
The directional control of the direct magnetic fields of the induction motor can improve the dynamic response speed of the motor, and its flux observation link is located in the feedback channel, so it has better parameter insensitivity than the indirect field-oriented control. In addition, the traditional method is to use the photoelectric encoder to obtain the speed signal needed for the flux observation, but in some bad conditions, the installation of the photoelectric encoder reduces the reliability of the motor, and improves the cost and the volume of the motor. In this paper, a new method is presented, which uses the S speed estimation algorithm of the model reference adaptive system (MRA) to observe the flux signal through the voltage and the current of the motor terminal and the calculated speed signal, so as to achieve the goal of the directional control of the direct magnetic field.
