This　paper　introduces　a　robust　sampled-data　(SD)　control　for　uncertain　parabolic　partial　differential　equation　(PDE)　system　with　Markov　jumping　parameters　(MJPs).　In　control　engineering,　in　order　to　fully　utilize　the　advantages　of　digital　technology　and　handle　the　uncertainties　in　the　system,　a　mode-dependent　robust　SD　control　strategy　presented　by　linear　matrix　inequality　(LMI)　based　conditions　is　given　on　basis　of　an　appropriate　Lyapunov　functional,　which　can　ensure　the　stochastically　exponential　stability　of　closed-loop　Markov　jumping　parabolic　PDE　SD　control　system.　Finally,　an　example　is　given　to　verify　the　effectiveness　of　the　proposed　method.
