In order to achieve that, a dynamic sensorless strategy is proposed to perform active disturbance rejection control. As a convex optimization problem, a novel reformulation of the problem is provided to compute optimal control. Accordingly, necessary less conservative conditions are established via Linear Matrix Inequalities. First, a sensorless active disturbance rejection design is proposed. Then, to carry out the control process, a robust dynamic observer\u2013predictive controller approach is introduced. Meanwhile, the PWM DC-DC switching power converters are examined as discrete-time Markovian switching systems. Considering that the system is subject to modeling uncertainties, time delays, and load variations as external disturbances, and by taking partial input saturation into account, the Lyapunov\u2013Krasovskii function is used to construct the required feasibility frame and less conservative stability conditions. As a result, the proposed design provides an efficient control strategy with disturbance rejection and time-delay compensation capabilities and maintains robust performance with respect to constraints. Finally, a PWM DC-DC power converter simulation study is performed in different scenarios, and the obtained results are illustrated in detail to demonstrate the effectiveness of the proposed approach.<\/jats:p>","DOI":"10.3390\/s23156936","type":"journal-article","created":{"date-parts":[[2023,8,4]],"date-time":"2023-08-04T09:28:29Z","timestamp":1691141309000},"page":"6936","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Dynamic Sensorless Control Approach for Markovian Switching Systems Applied to PWM DC\u2013DC Converters with Time-Delay and Partial Input Saturation"],"prefix":"10.3390","volume":"23","author":[{"given":"Abdelmalek","family":"Zahaf","sequence":"first","affiliation":[{"name":"Faculty of Technology Sciences, Constantine 1\u2014Fr\u00e8res Mentouri University, Constantine 25017, Algeria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9395-4417","authenticated-orcid":false,"given":"Sofiane","family":"Bououden","sequence":"additional","affiliation":[{"name":"Laboratory of SATIT, Department of Industrial Engineering, Abbes Laghrour University, Khenchela 40004, Algeria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammed","family":"Chadli","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Paris-Saclay, Univ Evry, IBISC, 91020 Evry, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilyes","family":"Boulkaibet","sequence":"additional","affiliation":[{"name":"College of Engineering and Technology, American University of the Middle East, Egaila 54200, Kuwait"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1147-4896","authenticated-orcid":false,"given":"Bilel","family":"Neji","sequence":"additional","affiliation":[{"name":"College of Engineering and Technology, American University of the Middle East, Egaila 54200, Kuwait"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6024-3643","authenticated-orcid":false,"given":"Nadhira","family":"Khezami","sequence":"additional","affiliation":[{"name":"College of Engineering and Technology, American University of the Middle East, Egaila 54200, Kuwait"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1760","DOI":"10.1109\/TCSI.2021.3053468","article-title":"Control of a buck DC\/DC converter using approximate dynamic programming and artificial neural networks","volume":"68","author":"Dong","year":"2021","journal-title":"IEEE Trans.
