Abstract

The invention discloses an intelligent warp knitting multi-speed electronic let-off system which comprises a digital PID master controller connected with a parameter setting input device, a frequency converter, a spindle speed encoder arranged on a spindle motor, and a beam speed encoder arranged on a beam motor, wherein the master controller is in drive connection with the spindle motor through the frequency converter; and an output end of the spindle speed encoder is connected with a feedback input end of the master controller through an electric signal. The system also comprises digital beam slave controllers; the slave controllers are multiple digital PID controllers in shunt feedback connection; each slave controller comprises a PID module, a single-neuron adaptive algorithm module and a fuzzy immunity optimization algorithm module; a feedback output end of each slave controller is connected with a feedback input end of the master controller through an electric signal; and an input end of each slave controller is connected with an output end of the master controller through an electric signal. The whole control system has higher intelligence and can meet the system control requirement for multi-speed high-precision high-speed frequent switching of the multi-speed electronic let-off system.

Description

technical field [0001] The invention belongs to the technical field of knitting machinery, and relates to an electronic let-off control system for a warp knitting machine, in particular to an intelligent warp knitting system based on a Fuzzy Immune (FI)-Single Neuron Adaptive PID (Single Neuron Adaptive PID, SNAPID) control algorithm. Multi-speed electronic let-off system. Background technique [0002] The let-off system is one of the most important components of the warp knitting machine. According to its different control forms, the let-off system is divided into mechanical let-off system (FAG), electronic let-off system with single and double speed fixed length (EBA), multi- For high-speed warp knitting electronic let-off system (EBC) and other types, the control performance of the let-off system directly affects the quality of warp knitting products and the number of patterns that can be woven. [0003] The feature and advantage of the multi-speed EBC electronic warp le...

[0008] Using such technology, if the requirements for the color and quality of the product are not too high, of course it can be used normally, but for warp knitting products with high requirements for the color and quality of the product, due to the characteristics of the process, the system requires high-precision, high-speed, frequent switching response performance. , and this technology only uses the conventional digital PID control system, although it can also be used, but the algorithm is simple, the degree of intelligence is not high enough, and the effect of use is not ideal.
