摘要：

As an extension of the Talk (Uniform Attractivity of Nonlinear Time-Varying Systems), this talk will present how to use the proposed framework to check uniform attractivity of switched nonlinear time-varying (NLTV) systems. Both arbitrarily switching and constrained switching cases will be addressed. This talk starts from the revision of switched NLTV systems with appropriate stability definitions. The definitions of persistent excitation (PE) condition and detectability will be provided in the context of switched NLTV systems. The concept of PE pairs and detectability pairs will be exploited for switched NLTV systems. A systematic procedure to check UA of switched linear-time-invariant system will be provided. With the help of this new framework, some new stability results can be obtained.
