The uncertain part of the model may be non-causal if the plant has time-delays possessing time-varying uncertainties. Note that, most of the robust controller design methods are based on the ``small-gain theorem'', which assumes the causality of the connected sub-systems. Because of this, some limitations on the plant may be required to ensure the causality of the uncertain part to design a robust controller. However, such an approach results in a conservative controller. In this study, allowing non-causal uncertain parts, optimal robust controller design problem for systems with multiple time-delays possessing time-varying uncertainties is considered. The problem is difficult, since these systems are infinite-dimensional and the uncertain parts are allowed to be non-causal. Since unstable controllers are not desired in practice, however, designed optimal controllers may be unstable, stable robust controller design algorithms are also considered. As a case study, the flow control problem in data-communication systems is handled.","brand":"LAP LAMBERT Academic Publishing","offers":[{"title":"Default Title","offer_id":54737260740950,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0925\/5829\/5382\/files\/product_image_9783847325376_1.jpg?v=1791119519","url":"https:\/\/www.momoxbooks.com\/products\/hakki-ulas-unal-robust-controller-design-9783847325376","provider":"momox","version":"1.0","type":"link"}
