Abstract：This paper proposed an adaptive super-twisting(ASTW)based sliding mode nonlinear control strategy for cooperative control of proton exchange membrane(PEM)fuel cell system.Firstly,the dynamic model of PEM fuel cell gas feeding system is developed,and the control problem of oxygen excess ratio,hydrogen excess ratio and pressure difference on both sides of membrane is formulated.Then the ASTW algorithm is proposed with the control gain regulated adaptively while suppressing the chattering.A Lyapunov function is built to prove the stability of this control strategy.Finally,simulation studies are conducted on a PEM fuel cell model built on Matlab/Simulink environment.The simulation results indicate that the developed ASTW control strategy has better dynamic control performance of oxygen excess ratio,hydrogen excess ratio and pressure difference on both sides of membrane,and strong chattering suppression ability,which is benefit to efficiency and stable operation of PEM fuel cell system.
