Speech title: Recent Advances in Event-Triggered Consensus of Multi-Agent Systems
Abstract: Event-triggered consensus of multi-agent systems has attracted tremendous attention from both theoretical and practical perspectives due to the fact that it enables all agents eventually to reach an agreement upon a common quantity of interest while significantly alleviating utilization of communication and computation resources. This seminar talk will provide an overview of recent advances in event-triggered consensus of multi-agent systems. First, a basic framework of multi-agent event-triggered operational mechanisms is established. Second, representative results and methodologies reported in the literature are reviewed and some in-depth analysis is made on several event-triggered schemes, including event-based sampling schemes, model-based event-triggered schemes, sampled-data-based event-triggered schemes and self-triggered sampling schemes. Third, an example is outlined to show applicability of event-triggered consensus in distributed secondary control for active power sharing and frequency regulation in islanded microgrids. Finally, some challenging issues on event-triggered consensus are proposed for future research.

Speech title: Design of a generalized sliding mode observer
Abstract: In this talk, the framework of a generalized sliding mode observer is presented for a wide range of second-order systems. It is seen that the conventional system state space representation is first augmented by adding the first-order dynamics of the system output. A new generalized sliding mode observer can then be designed in the sense that (i) the system output estimation error dynamics with a finite time convergence is used as the leader with the desired error dynamics; (ii) All of the state estimation error dynamics can then be driven to learn from the leader to achieve the finite converge of the state estimation errors. A few amazing findings and designs ensure that the observer system parameters can be on-line adjusted and thus both the system states and uncertain dynamics can be well estimated. Simulation and experimental results show the excellent performance of the proposed generalized sliding observer system.
