Title: Stabilizing Design of Switched Linear Systems

Abstract: In this talk, we focus on the problem of stabilization for switched linear systems. While much progress has been made, the problem is still largely open. We review the essential difficulties for solving the problem, including 1) non-existence of convex control-Lyapunov functions; 2) the one-subsystem-one-linear-feedback scheme is generally insufficient; and 3) finite-automaton-induced switching is generally insufficient. We introduce recent progress towards (partly) overcoming the difficulties.

Title:Control Barrier Functions for Safety-Critical Control of Dynamic Systems

Abstract: We are witnessing a new era of autonomy – from self-driving cars in the streets, to delivery drones in the sky, to exploration rovers on Mars. These autonomous systems are safety critical and involve the tight coupling between potentially conflicting control objectives and safety constraints. In this talk, I will describe a provably-safe optimization-based feedback control framework for the safety-critical control of dynamic systems where the safety condition is specified in terms of forward invariance of a set and verified via control barrier functions and the control objective is specified in terms of control Lyapunov functions. I will also demonstrate the application of this framework to robotic systems.

Title:Does R. E. Kalman’s Paradigm Still Works at the Big Data/AI Age?

Abstract: Professor R. E. Kalman was the founder and visionary intellectual leader of the field of mathematical system theory. His contributions to optimal control, optimal estimation and filtering, realization theory, and mathematical system theory are at the foundations of these fields. They have significantly influenced much of the subsequent developments. Their influence transcends well beyond system and control into diverse fields of engineering, mathematics, physical sciences, social sciences, and others. However, there have been very significant developments in science, engineering, technology, and society in the last few decades. It is clear that change will accelerate further in the coming decades. Thus, thinking about the relevance and implications of the Kalman’s paradigm of the control theory under the big data or the AI age, that might illuminate the path of the system and control research for the future. 

        This talk includes five parts. What is the Kalman’s Paradigm; The Challenges under the Kalman’s Paradigm the Problems We Face under the Big Data/AI Age; The Possible Solutions for the Post-Kalman Era; and the Conclusion.

Title:Deep reinforcement learning algorithms and applications

Abstract: Deep reinforcement learning (DRL), combines the merits of the decision ability of reinforcement learning and the perception ability of deep learning, is becoming a major artificial intelligence (AI) algorithm. Recently, Google DeepMind proposed several DRL algorithms to conquer the Atari video games, Go, and Starcraft II, thought to be several milestones in AI. The corresponding papers were also published in Nature and Science. Other teams in OpenAI and Microsoft also had great achievements in Dota2 video game and Mahjong separately with the strong support of DRL algorithm. This talk will introduce these shining hotspots, typical DRL algorithms, related applications, and discuss future potential directions.

Title:Secure Networked Control of Large-Scale Cyberphysical Systems using Cryptographic Techniques

Abstract: This work aims to create a secure environment for networked control systems composed of multiple dynamic entities and computational control units via networking, in the presence of disclosure attacks. In particular, we consider the situation where some dynamic entities or control units are vulnerable to attacks and can become malicious. Our objective is to ensure that the input and output data of the benign entities are protected from the malicious entities as well as protected when they are transferred over the networks in a distributed environment. Both these security requirements are achieved using cryptographic techniques. However, the use of cryptographic mechanisms brings additional challenges to the design of controllers in the encrypted state space; the closed-loop system gains and states are required to match the specified cryptographic algorithms. We propose a methodology for the design of secure networked control systems integrating the cryptographic mechanisms with the control algorithms. The approach is based on the separation principle, with the cryptographic techniques addressing the security requirements and the control algorithms satisfying their performance requirements.

Title: Secure Information Fusion in Cyber-Physical Systems


Abstract: The concept of Cyber-Physical System (CPS) refers to the embedding of sensing, communication, control and computation into the physical spaces. Today, CPSs can be found in areas as diverse as aerospace, automotive, chemical process control, civil infrastructure, energy, health-care, manufacturing and transportation, most of which are safety critical. Any successful attack to such kind of systems can cause major disruptions, leading to great economic losses and may even endanger human lives. The first-ever CPS malware (called Stuxnet) was found in July 2010 and has raised significant concerns about CPS security. In this talk we discuss how to design secure and efficient information fusion algorithms for CPS. We first consider the binary hypothesis testing problem with multiple sensors and design secure algorithm against an unknown set of Byzantine sensors. We further quantify the cost of adding security to the system and prove that our algorithm causes minimum impact on the performance in the absence of an attack. Next we consider the state estimation problem, and prove necessary and sufficient conditions, under which a convex optimization based estimator is secure against Byzantine attacks.
