Design Of Wire Winding Tension Controller Based On Fuzzy PID

In recent years,the field of industrial automation has experienced rapid development.There is a significant market demand for important components in the field of industrial automation,such as transformers,motors,and solenoid valves.Coils,as one of the core components,have also seen an increase in demand.Coils are usually manufactured using winding processes,and tension control is a crucial factor that affects the quality of coil winding.Good tension control during the coil winding process requires a system with fast response and good disturbance rejection capabilities.This paper proposes a fuzzy PID-based tension controller to improve the system’s disturbance rejection capabilities for the tension control problem in the coil winding process.Firstly,this paper analyzes the methods for generating and controlling tension.In response to the difficulty of traditional tension control methods to meet the requirements of high precision and high disturbance rejection performance,this paper proposes an active tension control system with a buffer.By analyzing the changes in the take-up speed and dancer arm angle of the system,a dynamic model of the dancer system is established.The dancer mechanism is composed of a spring as a buffer and the dancer arm.The rotation potentiometer detected dancer arm angle is used as a feedback signal to construct a closed-loop constant tension control system,thereby improving the precision and response speed of tension control.Secondly,in response to the problems of traditional PID control parameters unable to self-tune and poor control performance,this paper focuses on researching PID control strategy and fuzzy control strategy.Based on the tension control principle and expert experience,a fuzzy PID controller that can self-tune its parameters during the winding process is designed.The dynamic and static performance of the two controllers are compared through simulation using MATLAB software.The simulation results show that compared to the PID controller,the fuzzy PID controller reduces overshoot while ensuring response speed.When the system is disturbed by speed,it can quickly return to steady state with high steady-state accuracy.Finally,the hardware selection and software design of the tension control system based on the STM32 microcontroller and servo motor are carried out.By analyzing the functional requirements of the tension control system,the hardware composition is determined to be centered around the motor drive and analog detection circuits,and the schematic is drawn.By analyzing the tension control process,the main program with data acquisition,control,and fault detection functions is designed.Based on the WINFORM platform,the upper computer software implements functions such as system settings and curve drawing.In addition,experimental verification is carried out on the coil winding platform,and the results show that the tension controller designed in this paper has good control effect for the high-speed and strong disturbance coil winding process.
