In　this　paper,　we　consider　networked　iterative　learning　control　(NILC)　design　for　a　class　of　uncertain　discrete-time　nonlinear　systems　with　random　packet　dropout　and　communication　delay,　where　the　input-output　coupling　parameter　(IOCP)　is　assumed　to　be　unknown.　Firstly,　we　present　a　learning　scheme　for　the　unknown　IOCP.　Then　a　simple　NILC　scheme　is　developed.　It　is　strictly　proved　that　under　certain　conditions　the　developed　scheme　can　guarantee　zero-error　convergence.　Finally,　an　example　is　given　to　validate　the　findings.　Copyright　(C)　2019.　The　Authors.　Published　by　Elsevier　Ltd.　All　rights　reserved.
