Keil Project Code for STM32-Based PID Control of PEMFC Hydrogen Supply Pressure

This program is developed using Keil uVision5 (v5) and integrated with host computer-based data acquisition and control command delivery, achieving reliable PID closed-loop control of hydrogen supply pressure in the Proton Exchange Membrane Fuel Cell (PEMFC) system. Furthermore, the control system performance is optimized by adopting the optimal parameter set iteratively obtained from offline Particle Swarm Optimization (PSO) algorithm, which effectively enhances the accuracy and stability of hydrogen pressure regulation.
