Multi-machine cooperative intelligent control system for three-dimensional multi-layer profiling weaving process

Abstract

The invention discloses a multi-machine cooperative intelligent control system for a three-dimensional multi-layer profiling weaving process. The system comprises an oblique yarn guide mechanism, a heald frame, a beating-up mechanism, a coiling mechanism, a shaping mechanism, a cloth fell, a reed and a vertical yarn guide mechanism, and relates to the technical field of intelligent control. According to the multi-machine cooperative intelligent control system for the three-dimensional multi-layer profiling weaving process, by researching the three-dimensional multi-layer profiling weaving process technology, directional yarns are added into a yarn array in the z direction, and two sets of transverse fibers and longitudinal fibers which are perpendicular to each other are added into the face perpendicular to the interweaving thickness direction, so that a three-dimensional five-direction fiber intertexture is formed; according to the control method, a full-dimensional rotor state estimator is established to identify parameters such as rotor speed, stator and rotor resistance, instantaneous external load and the like of an induction motor, and torque current of the induction motor isdetermined by an external load identification result and speed and torque PID controller, and speed and torque control of the induction motor is realized.
