New Results on Practical Set Stability of Switched Nonlinear Systems
MetadataShow full item record
In this paper, we consider the practical set stability problem of a switched nonlinear system, in which every subsystem has one unique equilibrium point and these equilibrium points are different from each other. Based on the new concepts such as e -practical set stability and a t -persistent switching law, we explicitly construct a closed bounded set G and prove that under an appropriate t -persistent switching law the switched system is e -practically (asymptotically) set stable with respect to G. Finally, we present a numerical example to illustrate the results obtained.

Xu, Honglei (2009)Switched systems belong to a special class of hybrid systems, which consist of a collection of subsystems described by continuous dynamics together with a switching rule that specifies the switching between the subsystems. ...
Lin, Qun; Loxton, Ryan; Teo, Kok Lay (2013)A switched system is a dynamic system that operates by switching between different subsystems or modes. Such systems exhibit both continuous and discrete characteristics—a dual nature that makes designing effective control ...
Practical exponential set stabilization for switched nonlinear systems with multiple subsystem equilibriaXu, Honglei; Zhang, Y.; Yang, J.; Zhou, Guanglu; Caccetta, Louis (2016)This paper studies the practical exponential set stabilization problem for switched nonlinear systems via a t -persistent approach. In these kinds of switched systems, every autonomous subsystem has one unique equilibrium ...
