The systems have arbitrary relative degree and PD-type learning schemes are proposed. Under the effect of the PD-type learning schemes, the output-limiting trajectory is constructed. Based on the contraction mapping method, we show that the schemes can guarantee that the output of the iterative system converges uniformly to the output-limiting trajectory on the finite-time interval as the iteration index tends to infinity. A simulation example is used to illustrate the effectiveness of the proposed method.<\/jats:p>","DOI":"10.1177\/0142331218804299","type":"journal-article","created":{"date-parts":[[2018,10,23]],"date-time":"2018-10-23T18:04:22Z","timestamp":1540317862000},"page":"2555-2562","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["PD-type iterative learning control for linear continuous systems with arbitrary relative degree"],"prefix":"10.1177","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4728-0946","authenticated-orcid":false,"given":"Qin","family":"Fu","sequence":"first","affiliation":[{"name":"School of Mathematics and Physics, Suzhou University of Science and Technology, Suzhou, P.R.
