Abstract

A feedback linearization-based adaptive sliding mode controller (FLC-ASMC)was proposed to address the coordinated control of anode and cathode gas flow rates and pressures in a proton exchange membrane fuel cell (PEMFC) system. Considering the nonlinear and strongly-coupled characteristics of PEMFC system, the feedback linearization method was used to decouple the relationship between flow rates and pressures, and the anode-cathode pressure difference was hence able to be controlled within a reasonable range. The simulation results show that the traditional PID controller achieves about 85% control accuracy, the sliding mode controller (SMC) achieves 90%-92% control accuracy, while the FLC-ASMC achieves over 95% control accuracy, showing the best performance. The experimental verification confirms that the proposed controller can effectively control the pressure difference, and hence improve the system robustness and service lifespan.
