In　this　paper,　an　iterative　learning　output　feedback　control　method　is　proposed　for　parabolic　partial　differential　differential　equation　(PDE)　systems　with　time-varying　delay　and　random　packet　losses.　The　presented　control　strategy　contains　feedback　control,　which　is　used　to　improve　the　convergence　speed　of　the　iterative　learning　delayed　parabolic　PDE　systems.　Considering　the　limited　channel　bandwidth,　random　packet　losses　may　occur　in　delayed　PDE　system,　and　obey　Bernoulli　random　binary　distribution.　Firstly,　an　iterative　learning　control　under　spatial　local　averaged　measurements　is　given　for　PDE　systems　with　time-varying　delay　and　random　packet　losses　by　using　Lyapunov-Krasovskii　functional.　Subsequently,　some　sufficient　conditions　are　derived　to　ensure　the　convergence　for　delayed　parabolic　PDE　iterative　learning　control　systems　with　packet　losses.　Finally,　the　effectiveness　and　superiority　of　the　proposed　iterative　learning　control　method　are　presented　by　numerical　simulation　results.　©　2024　IEEE.
