Structure from Reasoning, Numbers from Search: On-Premise Open LLMs as Structural Priors for Coupled MIMO Controller Tuning
Researchers have explored the use of on-premise open-source large language models (LLMs) to improve the tuning of controllers for complex industrial processes. While traditional methods struggle with strongly coupled multi-input multi-output (MIMO) systems, LLMs can provide a structural prior, guiding the tuning process more effectively. The study found that LLMs excel in proposing counter-intuitive structures and achieving optimal control with significantly fewer evaluations compared to traditional optimizers, especially as system complexity increases.
