{"product_id":"robust-controller-design-von-hakki-ulas-unal","title":"Robust Controller Design:","description":"\u003cp\u003eSince an actual plant can not be modelled perfectly, robust controllers are needed due to the existing uncertainties. 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.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783847325376\"\u003e\u003ch3\u003eSystems with multiple uncertain time-delays\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783847325376","offer_id":39493657722973,"sku":"9783847325376","price":68.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/ff44315d-73c6-4869-af0e-66a28c553080.jpg?v=1770447952","url":"https:\/\/shop.autorenwelt.de\/en\/products\/robust-controller-design-von-hakki-ulas-unal","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
