Output Information Based Iterative Learning Control Law Design With Experimental Verification

Abstract: This paper considers iterative learning control law design using the theory of linear re-petitive processes. This setting enables trial-to-trial error convergence and along-the-trial performance to be considered simultaneously in the design. It is also shown that this design extends naturally to include robustness to unmodeled plant dynamics. The results from experimental application of these laws to a gantry robot performing a pick and place operation are given, together with a discussion of the positioning o… Show more

“…i.e., noncausal in p. This control law also requires all entries in the state vector to be available for measurement and [9] produces an alternative where the difference in the state vectors on two successive trials is replaced by the difference in the trial output vectors on the same two trials.…”

“…Given the finite pass length, repetitive processes are a more natural setting for ILC design and such designs have also seen experimental benchmarking [6], [7], [8]. These results were based on the use of a static state feedback and pass profile feed forward controller with the extensive application of Linear Matrix Inequalities (LMIs) as a numerical to calculate the required controller parameters.…”

“…Examples include classes of iterative learning control schemes [2,3] and iterative algorithms for solving nonlinear dynamic optimal control problems based on the maximum principle [4]. Iterative learning control algorithms designed using a repetitive process setting have been experimentally tested [5,6]. Also, there has been recent work on the use of this setting for the analysis of OL-Nash games with a gas pipeline application [7].…”
