Efficiency optimal control of PEMFC system considering thermal management

Thermal management of proton exchange membrane fuel cell (PEMFC) is the key factor affecting its safe, stable and efficient operation. Firstly, a PEMFC nonlinear simulation model coupled with thermal management subsystem is built. The nonlinear model is linearized and a control- oriented linear model is obtained. Then, a control strategy based on offset-free explicit model predictive control (EMPC) is designed and verified by software in the loop (SiL) platform, which realized accurate and real-time power tracking besides efficiency optimization under system constraints.
