报告题目：Multi-Agent Systems Based Distributed Control and Optimization in Smart Grids
内容简介：With the widespread integration of renewable distributed energy sources such as wind generation, photovoltaic and solar panels, a traditional electrical network has been experiencing a huge revolution towards a smart grid in various terms of generation, transmission, distribution and usage, and so on. Such a revolution poses new theoretical and technical challenges in operation and management of smart grids. To address these challenges, a multi-agent system based strategy is developed to address control and optimization issues in smart grids, showcasing its strong ability in improving efficiency, reliability and scalability. In this talk, some backgrounds on smart grids from the perspective of multi-agent systems are introduced. Second, a distributed secondary control scheme with an event-triggered communication mechanism is presented to ensure frequency regulation and active power sharing of AC islanded microgrids while significantly reducing the utilization of communication resources. Third, a multi-objective distributed optimization method is provided to address current sharing and voltage regulation in DC microgrids. Furthermore, a distributed energy management issue of smart grids maximizing the total social welfare that balances generation-side expanses, user-side payments, and transmission line costs is addressed. Finally, some challenging issues are discussed for future investigation.

报告题目：Safety and Reliability of AI Systems–Some Challenging Issues
内容简介：There are plenty of research and development going on in the field Artificial intelligence (AI), and one example is the development of autonomous vehicle that will impact our daily life and travel pattern. However, although there are many product and service examples that demonstrates the potential of AI, there are serious and challenging problems with AI applications. How to evaluate the reliability of a product incorporating AI is a difficult question that we should raise at the beginning. In this talk, we will share some thoughts and experience from systems engineering perspective and discuss some of these issues. Some of the research related to software reliability, hardware reliability and combined systems can be strongly linked to this. AI applications also rely on the availability of large amount of data that may have other issues such as data uncertainty and integration.

报告题目：Distributed Formation Flying of Multiple Spacecraft Systems over Switching Networks
内容简介：The existing results on formation flying of multiple spacecraft systems are obtained under two key assumptions that the desired formation is static, and the communication network among the spacecraft systems is static and connected. In this talk, we will report our recent research progress on the formation flying for multiple spacecraft systems by relaxing these assumptions. For this purpose, we decompose the formation flying problem into the attitude control problem and the position control problem. We first synthesize a distributed attitude controller based on a distributed observer for the leader system producing the desired attitude and a purely decentralized attitude controller, and then further synthesize a distributed position controller based on another distributed observer for the leader system producing desired formations and a purely decentralized position controller. Our overall distributed controller is able to achieve a variety of time-varying formations for multiple spacecraft systems over jointly connected switching networks.

报告题目：Efficient Reinforcement Learning-Based Control of Uncertain Nonlinear Systems
内容简介：Reinforcement learning (RL), which inspired by learning behaviour in nature, is a goal-oriented learning strategy wherein the agent learns the policy to optimize a pre-defined reward by interacting with the environment. For being data-driven, effectiveness in reaching optimal behavior, and adaptiveness to uncertain environment, RL has undergone rapid progress in control community. In this talk, we shall first discuss RL based disturbance rejection control for uncertain nonlinear systems with known nominal part. An extended state observer is first designed to estimate the system state and the total uncertainty. Based on the output of the observer, the control compensates for the total uncertainty in real time, and simultaneously, online approximates the optimal policy for the compensated system using a simulation of experience based RL technique. The approach does not require PE condition or probing signals. We further extend the study to systems with unknown nominal part, where a novel concurrent adaptive extended observer is developed to jointly estimate the parameters of the systems and the state, and a simulation of experience based RL is used to approximate the optimal policy.

报告题目：Research Trends in Developing Intelligent Unmanned Systems
内容简介：The research and market for the unmanned aerial systems (UAS), or drones, has greatly expanded over the last few years. It is expected that the currently small civilian unmanned aircraft market is likely to become one of the major technological and economic stories of the modern age, due to a wide variety of possible applications and added value related to this potential technology. Modern unmanned aerial systems are gaining promising success because of their versatility, flexibility, low cost, and minimized risk of operation. In this talk, we highlight some key techniques involved and research trends in developing intelligent autonomous unmanned aerial vehicles, which include task and motion planning, flight control systems, perception and data processing. Some industrial application examples will be used as illustrations.
