vector control
Vector control is the theoretical basis of high-performance control of modern motor, which can improve the torque control performance of motor. It divides the stator current into excitation component and torque component through field orientation, so as to obtain good decoupling characteristics. Therefore, vector control needs to control both the amplitude and phase of stator current. Because the stepping motor not only has the main electromagnetic torque, but also has the reluctance torque generated by the biconvex structure, and the internal magnetic field structure is complex, the nonlinearity is much more serious than the general motor, so its vector control is also more complex. The d-q axis mathematical model of two-phase hybrid stepping motor is derived. Taking the rotor permanent magnet flux as the directional coordinate system, the direct axis current id = 0 and the motor electromagnetic torque is directly proportional to IQ. The vector control system is realized by PC. In the system, sensors are used to detect the winding current and rotation position of the motor, and PWM is used to control the winding current of the motor. In this paper, the model of two-phase hybrid stepping motor based on magnetic network is derived, and the structure of its vector control position servo system is given. The neural network model reference adaptive control strategy is used to compensate the uncertain factors in the system in real time, and the efficient control of the motor is realized by maximum torque / current vector control.
