The　dynamic　response　of　fuel　cell　vehicle　is　greatly　affected　by　the　pressure　of　reactants.　Besides,　the　pressure　difference　between　anode　and　cathode　will　also　cause　mechanical　damage　to　proton　exchange　membrane.　For　maintaining　the　relative　stability　of　anode　pressure,　this　study　proposes　a　decentralized　model　predictive　controller　(DMPC)　to　control　the　anodic　supply　system　composed　of　a　feeding　and　returning　ejector　assembly.　Considering　the　important　influence　of　load　current　on　the　system,　the　piecewise　linearization　approach　and　state　space　with　current-induced　disturbance　compensation　are　comparatively　analyzed.　Then,　an　innovative　switching　strategy　is　proposed　to　prevent　frequent　switching　of　the　sub-model-based　controllers　and　to　ensure　the　most　appropriate　predictive　model　is　applied.　Finally,　simulation　results　demonstrate　the　better　stability　and　robustness　of　the　proposed　control　schemes　compared　with　the　traditional　proportion　integration　differentiation　controller　under　the　step　load　current,　variable　target　and　purge　disturbance　conditions.　In　particular,　in　the　case　of　the　DC　bus　load　current　of　a　fuel　cell　hybrid　vehicle,　the　DMPC　controller　with　current-induced　disturbance　compensation　has　better　stability　and　target　tracking　performance　with　an　average　error　of　0.15 kPa　and　root　mean　square　error　of　1.07 kPa.　©　2022,　China　Society　of　Automotive　Engineers　(China　SAE).
