Adaptive Iterative Learning Control of Time-delay Nonlinear Output-feedback Systems

In this paper, an adaptive tracking controller for a class of time-delay output feedback nonlinear systems is first proposed, an adaptive iterative learning control is then designed for repetitive time-delay output-feedback systems. The global exactly tracking on the specified time interval and the boundedness of all signals of the learning system are given via using the measurement output. In addition, the restrict condition on nonlinear functions (such as global Lipschitz condition) in the existing iterative learning control approach is relaxed. Simulation examples are provided to illustrate the application of the approaches.
