Temperature Control Algorithm for Packaging Heat Sealer Based on IWOA-PID

The packaging heat sealing machine is a commonly used equipment in industrial production. However, the temperature control of its horizontal and vertical sealing parameters is mostly still set by manual debugging, which is time-consuming and laborious. To address this issue, this paper proposes an Improved Whale Optimization Algorithm combing with PID to achieve self-tuning PID parameters. Firstly, the transfer function model of the heat sealer is established by the step response method, and then the WOA algorithm is improved to improve the convergence speed of the algorithm and the optimization results. Finally, the simulation comparison test is carried out in MATLAB and Simulink. The experiments demonstrate that the IWOA-PID algorithm proposed in this paper has a better control effect compared to the genetic algorithm, particle swarm algorithm, and whale optimization algorithm. This finding is significant for the temperature control of packaging heat sealing machines.
