Abstract :
Acting as a supervision or optimization module for a local controller, indirect iterative learning control (ILC) can improve closed-loop performance along the batch direction. In particular, if the set-point for the local controller is updated, this type of indirect ILC is termed set-point-related (SPR) indirect ILC. SPR indirect ILC has shown excellent performance; however, there is no reported work on stability analysis for this method. Based on a 2-dimensional (2D) framework, a sufficient condition for asymptotical stability of SPR indirect ILC is derived in this paper.
