Abstract

The invention discloses a tension fuzzy PID (Proportion Integration Differentiation) control method for a recoiling machine. In the method, current ring-speed ring double closed-loop control is adopted, a speed regulator and a current regulator are arranged respectively in the feedback elements of a current ring and a speed ring, six fuzzy controllers are adopted for controlling the PID parameters of the current ring and the speed ring, two inputs and one output are adopted for each fuzzy controller, input quantities are deviation values E and deviation change rates Ec of set tension, and output quantities are P, I and D parameters of a current controller and a speed controller respectively; three corresponding fuzzy controllers are connected in series respectively in front of the current regulator and the speed regulator, a subordinating degree function is regulated continuously in the running process of the recoiling machine, automatic control over the tension of the recoiling machine is realized by controlling the rotating speed of a motor and armature current, and the tension of the recoiling machine is regulated automatically and is always kept constant; and as proved by simulink simulation, the method has the advantages of quick response, high regulating capability, high robustness and effective improvement on the control effect.

Description

technical field

[0001] The invention relates to a tension control method of a coiler, which realizes the indirect control of the tension of the coiler by controlling the PID parameters of the current loop and the speed loop of the coiler by a fuzzy controller. The invention can be widely used in light industry related fields such as fiber, paper making, plastic film, electric wire, printed matter, magnetic tape and metal product industry. Background technique

[0002] In the metallurgical industry, the coiler is an auxiliary equipment in the steel rolling workshop that coils hot-rolled or cold-rolled steel into a coil. The coiler is used to bend the steel into a coil, so as to increase the weight of raw materials, increase the rolling speed, Reducing the temperature difference between the head and tail of the rolled piece provides a powerful condition, which leads to the improvement of product output and quality; in addition, the coiled rolled material is easy to transport, ...
