Stability Analysis and Design for Nonlinear Singular Systems

By: Chunyu Yang,Qingling Zhang,Linna Zhou

Singular systems which are also referred to as descriptor systems, semi-state systems, differential- algebraic systems or generalized state-space systems have attracted much attention because of their extensive applications in the Leontief dynamic model, electrical and mechanical models, etc. This monograph presented up-to-date research developments and references on stability analysis and design of nonlinear singular systems. It investigated the problems of practical stability, strongly absolute stability, input-state stability and observer design for nonlinear singular systems and the problems of absolute stability and multi-objective control for nonlinear singularly perturbed systems by using Lyapunov stability theory, comparison principle, S-procedure and linear matrix inequality (LMI), etc. Practical stability, being quite different from stability in the sense of Lyapunov, is a significant performance specification from an engineering point of view. The basic concepts and results on practical stability for standard state-space systems were generalized to singular systems. For Lur’e type descriptor systems (LDS) which were the feedback interconnection of a descriptor system with a static nonlinearity, strongly absolute stability was defined and Circle criterion and Popov criterion were derived. The notion of input-state stability (ISS) for nonlinear singular systems was defined based on the concept of ISS for standard state-space systems and the characteristics of singular systems. LMI-based sufficient conditions for ISS of Lur’e singular systems were proposed. Furthermore, observer design for nonlinear singular systems was studied and some observer design methods were proposed by the obtained stability results and convex optimization algorithms. Finally, absolute stability and multi-objective control of nonlinear singularly perturbed systems were considered. By Lyapunov functions, absolute stability criteria of Lur’e singularly perturbed systems were proposed and multi-objective control of T-S fuzzy singularly perturbed systems was achieved. Compared with the existing results, the obtained methods do not depend on the decomposition of the original system and can produce a determinate upper bound for the singular perturbation parameter.

Railways and Sustainable Low-Carbon Mobility in China

By: Linna Li

This book explores the role of railways in developing sustainable low-carbon mobility by analyzing the intermodal relationship between railways and other transport modes. Focusing on geographical and governance perspectives, and taking China as a case study, it analyzes the competition and cooperation between and integration of railways and other transport modes, in order to provide guidance on future sustainable transport development. Firstly, the book examines the contribution of railways to low carbon emissions in China over recent decades by estimating the carbon dioxide emissions from various transport modes in China at national and regional levels using decomposition analysis. It then discusses the current competition and cooperation between railways and other transport modes, as well as their integration and the impact of their relationship on climate change. It also highlights how the competition between railways and other transport modes may change the passenger flows between city pairs and so alter transport carbon emissions and examines how cooperation and integration could improve passengers’ travel experience while at the same time reducing carbon emissions. Lastly, it addresses the implications for future sustainable transport development based on institutional analysis. Presenting multidisciplinary, sustainable transport research on the role of railways in reducing carbon emissions, and also offering policy recommendations for developing low-carbon, integrated transport in the future, this book is a valuable reference resource for graduates, researchers, and government managers responsible for transport development, urban planning and environmental policy.
