SmartControl: Interactive PID controller design powered by LLM agents and control system expertise

SmartControl is an interactive PID controller design tool powered by the novel integration of Large Language Model (LLM) agents and control system expertise. Users articulate system performance requirements in natural language, which the software converts into numerical targets. Optimal PID gains are determined using Particle Swarm Optimization and Differential Evolution algorithms, and the system’s step response is simulated and presented graphically. The result evaluation module analyses performance data via an LLM agent, providing interactive feedback and educational support. Furthermore, the tool generates MATLAB code and PDF reports, thereby focusing its utility on efficient control system design workflows in academic research and simulation-driven design studies.
