Linear State-Feedback Control of a Buck-Boost Converter Using Passivity Technique

Knowledge and Technology Transfer: Novel Results While Teaching Advanced Courses

“…Furthermore, due to the availability of computer networks and communication technologies and planned international co-operation, developing countries can achieve their fair share in intellectual services for automation and control . This paper validates the above argument through an analysis discussion of the authors' recent control results in applications to electrical power systems and power electronics (Li and co-authors, 2003;Li, 2003;Serafimovski, 2001;Serafimovski and Dimirovski, 2004) while teaching advanced courses on control to graduate students. To shed light on the aforementioned results, first the respective problems and background research are outlined in Section 2.…”

“…The other case study, while teaching advanced control theory, that yielded a novel control design and implementation (Serafimovski, 2001) is the voltage stabilization of buck-boost converter (BBC; Figure II) via state-feedback regulation using passivity technique (Sira-Remirez and co-authors, 1997). Plant is a switched-mode dc-dc converter that is inherently non-linear and variable-structure system because of elements such as diodes and switches (Bose 1997;Mohan and co-authors, 1995).…”

“…If otherwise, a largesignal model is required for proper analysis and synthesis (e.g., Chen and Cai, 1990;Sira -Ramirez and co-authors, 1997). Based on a similar study for boost converter by Grasa (2000), Serafimovski (2001) carried out a large-signal design has been elaborated for the buck-boost topology.…”

“…The novel passivity-technique based control design for a buck-boost dc-dc converter (BBC device; see Figure II) has been developed in (Serafimovski, 2001) and further studied and asymptotic stability proved (Serafimovski and Dimirovski, 2004). …”

“…Here, the gain coefficient max α is obtained by a special analysis of the BBC physics (Serafimovski, 2001 …”
