Performance Optimization of Winding Tension PID Control Based on Improved Whale Algorithm
The parameters of PID controller determine the stability and speed of tension control system,so it is important to study the parameter tuning optimization of classical PID controller in winding tension control. The PID tension controller based on the modified whale algorithm is designed by combining PID and modified whale optimization algorithm with winding tension control as an entry point. The improved whale algorithm (L-WOA) is combined with PID in order to improve its convergence speed and convergence accuracy when rectifying the PID parameters. A mathematical model and a dynamic torque balance equation are developed to analyze the effect of wire speed and web diameter on web tension. The parameters are optimized using the modified whale algorithm and various other algorithms,respectively,and the results show that the PID controller optimized by the improved whale algorithm proposed in this paper has the advantages of rapid response,more steady output,sturdy anti-interference ability and better robustness when the PID controller is controlled.
