Plenary Lecture: The Undying PID Control: From Folklores to an Explainable Theory

Abstract: For well over a century, PID control stood out as the most favored method for its simplicity, robustness, ease of implementation and cost-effectiveness. It continues to demonstrate its sustained power and inexplicable charm, serving an awe-inspiring testimony to its incredible vitality and widespread acceptance by industrial control and automation communities. Traditionally, the design and implementation of PID controllers are conducted by somewhat ad hoc, trial and error tuning methods. One must then wonder, with its seemingly simplistic structure and empirical rules of design, why on earth PID control performs so well? How good can it get to be? Would it continue to be relevant in an AI-centric era? In this talk I shall attempt to provide an anecdote and an analysis to these contemplations, using system robustness--arguably the most important goal in feedback design--as a pilot problem. We address such canonical problems as gain, phase, and delay margins, which define in different manners the largest range of unknown, variable parameters that a system can tolerate to maintain stability robustness. I shall present our recent triumphs in determining these margins achievable by PID control, and argue in favor of a least amount of PID insight vis-a-vis massive AI computations. The solutions to the problems, much to our delight, provide analytical justifications to folk wisdom of one hundred years on PID controller tuning and design.

Prof. Kenji Fujimoto
(Keynote Speaker)

Kyoto University, Japan

Keynote Lecture: Passivity based sliding mode control for electro-mechanical systems

Abstract: Both passivity based control and sliding mode control are well established useful techniques for nonlinear systems. Although they have been considered to be completely incompatible methods, there are actually some points of contact between them. This presentation shows recent results on their integration based on the port-Hamiltonian framework. Passivity based control is a method to find energy based Lyapunov function candidates for physical systems. It can generate Lyapunov functions for several objectives such as trajectory tracking control and/or those for output feedback control by a similar way to the standard artificial potential function method. On the other hand, sliding mode control is a technique to design a closed loop system with fast convergence by employing discontinuous high gain feedback without constructing any explicit Lyapunov function for the closed loop system. This presentation gives a brief summary on the author's developments on passivity based control with a recent attempt to integrate the two different techniques by employing a special class of non-smooth Lyapunov functions. This idea allows for highly flexible controller design that smoothly complements passivity based control and sliding mode control. Furthermore, it will also cover how the proposed framework is applied to electro-mechanical systems as well as conventional mechanical ones.

Prof. Zhengkun Yi
(Invited Speaker)

Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences, China

Invited Lecture: Biomimetic Tactile Sensing: from Humans to Robots

Abstract: As robots move from laboratories to domestic environments, they will be required to perform manipulation tasks in unstructured environments. Such robots must be able to achieve sophisticated interactions with the environment and to perform complex tasks such as grasping objects with arbitrary unknown shapes. The sense of touch is a fundamental capability of robots to achieve these tasks. How to endow robots with human-like tactile abilities has attracted increasing attention in both academia and industry. In recent years, tactile sensors such as BioTac, GelSight, and TacTip have surpassed human tactile perception capabilities in terms of resolution, response speed, and measurement range, but there is still a big challenge to achieve human-like tactile sensation. One of the main difficulties is how to achieve precise understanding and efficient use of tactile signals. This talk will first introduce the human tactile perception and technologies of robotic tactile perception, and then cover the recent research progress including bionic tactile perception, sensor drift compensation, and robot tactile interaction based on artificial intelligence and brain-like intelligence methods.

Invited Lecture: Multi-robot exploration of spatial-temporal varying fields

Abstract: The exploration of unknown spatial-temporal varying fields, especially in areas that are inaccessible or hostile to humans, presents a fundamental and challenging problem in the field of mobile robots. In such scenarios, mobile sensor networks consisting of coordinated groups of mobile robots offer promising solutions. This talk presents the co-design of distributed sensing and cooperative control algorithms for mobile sensor networks, specifically tailored for the exploration of unknown spatial-temporal varying fields. The speaker will present online state estimation and parameter identification algorithms designed for distributed parameter systems using mobile sensor networks with reduced computational and communication costs. Various applications will be discussed, including source seeking, boundary following, and map reconstruction. The potential applications of this work extend to areas where resources are constrained, such as search and rescue operations, chemical contamination localization, and wildfire detection and monitoring.

Prof. Fei Miao
(Invited Speaker)

University of Connecticut, USA

Invited Lecture: Learning and Control for Safety, Efficiency, and Resiliency of Cyber-Physical Systems

Abstract: The rapid evolution of ubiquitous sensing, communication, and computation technologies has contributed to the revolution of cyber-physical systems (CPS). Learning-based methodologies are integrated to the control of physical systems and provide tremendous opportunities for AI-enabled CPS. However, existing networked CPS decision-making frameworks lack understanding of the tridirectional relationship among communication, learning and control. It remains challenging to leverage the communication capability for the learning and control methodology design of CPS, to improve the safety, efficiency, and robustness of the system. In the first part of the talk, we present our research contributions on learning and control with information sharing for networked CPS. We design the first uncertainty quantification method for collaborative perception of connected autonomous vehicles (CAVs) and show the accuracy improvement and uncertainty reduction performance of our method. To utilize the information shared among agents, we then develop a safe and scalable deep multi-agent reinforcement learning (MARL) algorithms to improve system safety and efficiency. We validate the benefits of communication in MARL especially for CAVs under challenging mixed traffic scenarios. To motivate agents to communicate and coordinate, we design a novel stable and efficient Shapley value-based reward reallocation scheme for MARL. In the second part of the talk, we briefly present our research contributions on data-driven robust optimization for autonomous mobility-on-demand (AMoD) systems and CPS security.
