摘要：
Based on the analysis of the new requirements of intelligent manufacturing for PID tuning and the challenges and difficulties faced by PID tuning, this paper proposes an adaptive and autonomous PID tuning intelligent optimization method by deeply integrates and coordinates the modeling, control and optimization in automation and deep learning and reinforcement learning in artificial intelligence. The proposed method contains the digital twin model of the PID control process based on end-edge-cloud collaboration and the PID tuning algorithm combining reinforcement learning and digital twin model. Furthermore, the PID tuning intelligent system is developed by combining the end-edge-cloud collaboration technology of Industrial Internet with the PLC control system, and has been successfully applied to the energy intensive equipment — Fused magnesium furnace. This system operates safely, reliably and optimally, achieving remarkable effects in energy conservation and emission reduction. Finally, the further research content in the intelligent research direction of control system is proposed. © 2023 Science Press. All rights reserved.
