Researchers have developed a novel framework that leverages Large Language Models (LLMs) to automate the tuning of PID controllers in chemical processes. This approach mimics the iterative workflow of human engineers, using LLMs to diagnose process responses, adjust tuning parameters, and validate results. The framework was tested with both large and small language models, including DeepSeek-V4-Flash, Qwen3.7-Plus, and a fine-tuned Qwen3-0.6B. The fine-tuned Qwen3-0.6B, enhanced with physics-informed optimization, achieved a high success rate of 94.0% on various test cases, demonstrating significant potential for improving control system performance and reliability.
