stability analysis and stabilization of semi-Markov jump linear systems with unavailable sojourn-time information

science China(Information sciences) 2024年第7期67卷 211-223页

作者： Xiaotai WU yang tang shuai MAO ying ZHAO school of Mathematics and Physics Anhui Polytechnic University Key Laboratory of Advanced Control and Optimization for Chemical Processes Ministry of EducationEast China University of Science and Technology

This study addresses the stability and stabilization problems of discrete-time semi-Markov jump linear systems(s-MJLss) with unavailable sojourn-time information. The sojourn-time probability mass functions(s-TPMFs) of discrete-time semi-Markov chains are no longer confined to the geometric distribution, and it is difficult to obtain accurate and comprehensive information for s-TPMFs in practice. This is because s-TPMFs are usually deduced from the statistical characteristics according to the sampled-data, while adequate samples are often costly and time consuming. In this study, when the s-TPMFs for semi-Markov chains are assumed to be unavailable, the σ-error mean square stability is investigated for discrete-time s-MJLss with some widely used assumptions; for semi-Markov chains, only the transition probability matrix of the embedded chain is used. In addition, the existence conditions of the effective controller are provided for closed-loop systems without using the information of s-TPMFs. Numerical examples are presented to illustrate the validity of the obtained theoretical results.
