Yarn electronic forming position closed-loop control method, system, medium and equipment

The invention provides a yarn electronic forming position closed-loop control method and system, a medium and equipment, and the method comprises the steps: parameter recognition: employing a self-learning recognition mode to obtain key electromechanical parameters on a turning path of a yarn electronic forming machine, comprise parameters in an equation relation between a quadrature-axis current value of a yarn electronic forming servo motor and an acceleration value of a yarn electronic forming yarn guide nozzle; and an electronic forming position closed-loop control step: when the servo motor performs electronic forming U-turn, a model-based position closed-loop control mode is adopted, calculation is performed by using the key electromechanical parameters obtained by parameter identification according to the motion model before an error occurs, and a target control strategy of the motor is obtained to control the motor. The method not only can ensure that the real-time position precision meets the high re
