报告地点: 数学院大会议室341
内容摘要：In this talk, the problem of feedback control for a class of uncertain nonlinear systems with event-triggered input is considered. The considered system contains not only unknown system parameters, but also general nonlinear functions which are not required to be globally Lipschitz, in contrast to most of the existing results in the area. Besides providing two different event-triggered strategies without input-to-state stable (ISS) assumption with respect to the measurement errors, a new way to encode and decode the event-triggered control signals is proposed to further decrease the communication rate. It is shown that the boundedness of all the signals is ensured and the output signal can be regulated to an adjustable compact set.

报告题目： Distributed localization and control for swarm robots
报告人: 林志赟 (杭州电子科技大学)
报告时间: 6月10日上午9:00-10:00
报告地点: 数学院大会议室 341
内容摘要： In many applications, a network of multiple autonomous agents holds eminent promises to achieve a level of performance, capability, robustness, and efficiency beyond what a single agent can provide. However, to be advantageous, multiple agents have to work in an organized manner. Basic requirements include localizing the agents in the world coordinate system, achieving certain desired formation shape, etc. This talk is going to present several results regarding distributed localization and formation control. Its aim is to provide a unified framework for both distributed localization and formation control in terms of graph Laplacian. Graph connectedness will be discussed to ensure solvability of these problems, followed by distributed algorithms, for which global convergence is assured.

报告题目：Exponential stabilization of reaction-diffusion systems via intermittent boundary control
报告人: 吴开宁(哈尔滨工业大学(威海))
报告时间: 6月10日下午2:30-3:10
报告地点: 数学院大会议室341
内容摘要：This talk considers the exponential stabilization for reaction-diffusion systems (RDSs) by means of intermittent boundary control. For the case where all system states are available, a state-dependent intermittent boundary controller is designed, and a sufficient condition ensuring the exponential stability of RDSs is presented by employing spatial integral functional method and Poincare's inequality. For the case where system states are not fully accessible, a boundary observer is proposed to estimate the system states, and an observer-based intermittent boundary controller is provided such that the considered system is exponentially stable. Furthermore, an observer-based intermittent boundary controller is designed for the robust exponential stability of uncertain RDSs. Simulation examples are presented to show the effectiveness and potential of our theoretical results.

报告题目：Intermittent Stochastic Stabilization Based on Discrete-Time Observation with a Time Delay
报告人: 刘磊 (河海大学)
报告时间: 6月10日下午3:10-3:50
报告地点: 数学院大会议室341
内容摘要：This talk is corned with the stochastic stabilization via hybrid control strategies. First, a sufficient criterion on stochastic stabilization based on discrete-time observation with a time delay is derived. Next, with the aid of an established dynamical property for the non-autonomous system, a sufficient criterion is derived to ensure the intermittent stochastic stabilization based on discrete-time observation with a time delay. Finally, simulation on a numerical example is performed to illustrate the theoretical results.
