This paper proposes a novel networked iterative learning control (NILC) scheme with adjustment factor for a class of discrete-time uncertain nonlinear systems with stochastic input and output packet dropout modeled as 0-1 Bernoulli-type random variable. Firstly, the equivalence relation between the realizability of controlled system and the input-output coupling parameter (IOCP) is established. Secondly, in order to overcome the main obstacle arising from the unknown IOCP, an identification technique is developed for it. Thirdly, it is strictly proved that, under certain conditions, the tracking errors driven by the developed NILC scheme are convergent to zero along iteration direction in the sense of expectation. Finally, an example is given to demonstrate the effectiveness of the proposed NILC scheme and the merits of adjustment factor.
