Drive control method and system for limited rotation angle torque motor

Abstract

The present invention provides a drive control method and system for a limited-rotation-angle torque motor, which determines whether the motor is in the state of normal output torque by analyzing the motion image corresponding to the motion of the target object driven by the motor; meanwhile, collects the motor speed and motor output of the motor Power, to determine the actual operating torque of the motor, so as to judge whether the current output torque of the motor meets the rated operating state, and finally, according to the actual operating torque, determine the adjustment value of the voltage applied to the motor, so as to restore the motor to the rated operating state In this way, the effective closed-loop control of the motor operation can be realized, so as to ensure that the motor can always directly drive different loads in the rated operation state and improve the accuracy and reliability of the motor operation control.

Description

technical field [0001] The present invention relates to the technical field of motor control, and in particular, to a drive control method and system for a motor with limited rotational angle torque. Background technique [0002] The limited angle torque motor refers to a motor that can rotate quickly and accurately position within a limited angle range, and the limited angle torque motor can output a large torque, so as to facilitate the large-scale driving of the load within the limited angle range. . Limited angular torque motors are widely used in high-precision electrical servo systems such as aviation servo valves, steering gear actuation, robot joints, radar antennas and airborne turrets to directly drive loads within a limited rotation angle range. The torque output by the limited angle torque motor is related to the magnitude of the DC voltage applied to the limited angle torque motor. At present, a constant voltage is applied to the limited angle torque motor, bu...

Problems solved by technology

At present, a constant voltage is applied to the limited-angle torque motor, but in the actual operation of the limited-angle torque motor, due to its own internal mechanical loss, etc., the limited-angle torque motor may not be able to output a large enough torque, resulting in a limited angle. Torque motor not working properly

In the existing technology, the DC voltage applied to the motor with limited torque is changed by manual adjustment, which cannot effectively ensure that the motor always outputs the rated torque, and also greatly reduces the degree of automation of the motor operation, thereby reducing the motor's performance in the field of precision instruments.
