Abstract :
This paper considers the robustness of a gradient-based iterative learning control (ILC) algorithm to ensure monotonic convergence with respect to the mean square value of the error time series. The paper provides necessary and sufficient conditions for robust monotonic convergence and sufficient frequency domain conditions for robust monotonic convergence on finite time intervals.
