Considering an uncertain plant in iterative learning control (IL C), robust convergence and robust stability are important issues. Since the feedback controller robustly stabilizes the uncertain plant and has an e ect on the convergence, it plays as signi® cant a role as the learning controller does in the IL C system. To deal with both convergence and(More)
— A repetitive controller has been applied owing to its prominent capability for attenuating periodic disturbances and/or tracking periodic reference commands. A repetitive controller is generally added on the existing feedback control system to improve the tracking performance. However, the repetitive controller has been designed without utilizing the(More)
