Abstract
Electrohydraulic servo systems play a critical role in the aviation field and are widely used in key subsystems such as flight control, braking systems and nose wheel steering systems, directly affecting the safety and reliability of aircraft operations. However, current aviation electrohydraulic servo systems commonly rely on high-precision servo valves that feature extremely fine internal structures and vulnerability towards oil contamination, suffering from relatively low reliability, and require complex manufacturing, assembly, and calibration processes. Discrete digital hydraulics has emerged as a novel servo control technology. Owing to its advantages including simpler and more robust components, higher system flexibility, and inherent fault-tolerant capability, it has the potential to fundamentally overcome the limitations of conventional servo valves and provide a new feasible method for high-reliability hydraulic servo control in aviation applications.
Our research group has been devoted to the development of discrete digital hydraulic technologies through a systematic innovation framework encompassing new components, new control methods, and new system architectures. We have successfully developed miniature dual-driven high-speed on/off valves, achieved breakthrough in high-precision control strategies based on multi-layer discrete variable gain modulation, and designed several discrete digital hydraulic control architectures. These achievements have been applied and have yielded remarkable results, significantly enhancing the reliability and safety of aviation equipment.

Resilience in Multi-Agent Systems: From Fault Diagnosis to Tolerant Control and Toward a Game-Theoretic Framework

Prof. Bin Jiang Nanjing University of Aeronautics and Astronautics, China |
Abstract
In recent years, the growing complexity of multi-agent systems has made them increasingly susceptible to operational faults spanning both individual agent failures and communication disruptions, which directly compromise system stability and safety. Consequently, the demand for resilient multi-agent systems has intensified, driving significant research attention toward integrated fault diagnosis and fault-tolerant control. This talk presents a unified framework for achieving resilience through fault diagnosis, fault-tolerant control and fault-tolerant game control. The fault diagnosis module introduces a distributed nonlinear fault diagnosis design, enhanced by an event-triggered mechanism to improve efficiency and reduce communication load. In the fault-tolerant control module, theoretical advances are synthesized from fully actuated system theory, adaptive methods, and prescribed performance control, enabling robust recovery and sustained cooperation under faults. To further achieve the stability and optimal performance of multi-agent systems, the fault-tolerant game control is developed. Above results are applied to both homogeneous and heterogeneous multi-agent systems, with experimental validation provided through cooperative fault-tolerant control demonstrations in actual unmanned formation platforms.

Physics-informed learning and control of mixed-autonomy traffic

Abstract
Road infrastructure remains significantly underutilized in current traffic systems. Mixed-autonomy traffic, where connected and automated vehicles (CAVs) interact with human-driven vehicles, offers a unique opportunity to improve system-level efficiency, resilience, and safety. In this context, CAVs can be leveraged not only as transportation agents but also as distributed sensors and actuators, enabling real-time state estimation and feedback control of large-scale traffic networks. This presentation introduces a physics-informed learning and control framework for mixed-autonomy traffic systems. By embedding traffic flow dynamics into machine learning models, we develop structured, data-efficient representations that generalize across operating conditions while preserving physical consistency. These models enable the design of scalable feedback control strategies that proactively mitigate congestion and respond to disturbances under uncertainty. We provide a comparative analysis of model architectures from a control perspective, highlighting trade-offs in expressiveness, interpretability, and robustness. Furthermore, we address the challenges of human–automation interaction by integrating formal safety guarantees into the control design and by incorporating teleoperation as a supervisory fallback mechanism in safety-critical scenarios. The proposed framework is validated through extensive real-world demonstrations conducted in collaboration with Swedish industry partners, illustrating its potential for deployment in next-generation intelligent transportation systems.

MAD Games: Multi-Agent Dynamic Games - Lessons from the Limits of Autonomous Racing

Prof. Rahul Mangharam University of Pennsylvania, USA |
Abstract
The critical challenge in deploying autonomous systems is achieving peak performance without compromising safety. Autonomous racing crystallizes this challenge, as it punishes timid policies and demands robust, adaptive strategies in multi-agent settings. Current approaches often fail by either oversimplifying the behavior of other agents or lacking mechanisms for real-time adaptation.
This talk presents research that pushes the boundaries of perception, planning, and control. We will explore how to develop highly competitive agents through:
Adversarial Training: Leveraging game theory and distributionally robust online adaptation to create agents that dynamically balance safety and assertiveness.
Adaptive Safety: Using conformal prediction, control barrier function and imitation learning we show how multiple imperfect experts train an AI to perform better than any single expert.
Safe MPC Frameworks: Implementing iterative control strategies for nonlinear stochastic systems to handle constrained, real-world uncertainty.
All research is implemented on our RoboRacer.ai platform—1/10th the size, but 10x the fun. The key takeaway is a deeper understanding of how to build and validate safe autonomous systems for complex, interactive environments.
