Networked iterative learning control for systems with packet dropout and communication delay ?

摘要

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.
