报告1题目：A tale of two theories: adaptive stabilization and adaptive synchronization by structural matrix 

报告1摘要：

In this talk we consider distributed adaptive stabilization for uncertain multivariable linear systems with a time-varying diagonal matrix gain. We show that uncertain multivariable linear systems are stabilizable by diagonal matrix high gains if the system matrix is an H-matrix with positive diagonal entries. We apply the adaptive distributed stabilization approach to adaptive synchronization for large-scale complex networks, which consist of nonlinear node dynamics and time-varying coupling weights. A unified framework for adaptive synchronization is proposed that includes several general design approaches for adaptive coupling weights to guarantee network synchronization.

In the second part of the talk, we present a time-varying matrix solution to address the Brockett decentralized stabilization problem, an open problem in system and control proposed by Roger Brockett in 1999. 

报告2题目：Safe stabilization: recent development and applications of control barrier functions

报告2摘要：

Safety-critical control has received increasing attention in the system and control community, which has been popularized by promising techniques involving control barrier functions (CBFs). This talk will review and discuss recent developments of CBFs in safety-critical control.

In particular, we discuss three topics of CBFs in safety-critical control: (1) we will present graphical interpretation and universal formula for safe stabilization; (2) we will conduct a comparative study of artificial potential fields and CBF-based safety filters for safe navigation; (3) we will apply the CBF approach for quadrotor stabilization with safety guarantees.
