A Series Connection Scheme of Iterative Learning Control Based on Disturbance Observer

Abstract:

In order to reject non-repetitive disturbance and improve the performance of iterative learning control, a series connection of feedback controller and ILC system with disturbance observer is presented. The random disturbance and uncertain model in ILC are studied. The simulation experiments indicate that DOB can reject non-disturbance and decrease the affect of uncertain model in ILC. The system is verified to be effective for promoting tracking performance and rejecting the non-repetitive disturbance in ILC.
