Flow-Based Cyber-Physical Systems
Flow-based systems are physical systems, such as water distribution systems, oil & gas pipelines, and human cardiovascular systems, that can be modeled as a flow network in which a physical entity, e.g., water, oil or blood, flows through the edges of the network. Observing these critical systems for monitoring and exploration purposes is of paramount importance. This talk highlights the challenges and approaches to study flow-based systems using a Cyber-Physical Systems (CPS) approach. The path towards such a CPS approach faces several research challenges. A CPS has three key components – Communication, Computation, and Control. First, there is a need to encompass the existing technology into an efficient system design (e.g., designing an efficient system design to incorporate mobile wireless sensors moving through water pipelines to monitor Water Distribution Systems). From the communication perspective, traditional networking paradigms may be insufficient to address the challenges in certain environments. From the computation perspective, there is a need to process the information collected and optimize the cost and benefit of monitoring (e.g., minimizing the number of sensors to achieve a sensing coverage). From a controls perspective, the challenge is to take efficient control decisions to achieve a desired performance (e.g., controlling the flow of water to drive sensors to specific regions). The talk will use Water Distribution Systems as a primary case study and include discussions of on-going efforts in applying the approach to other flow-based systems.

Collision Free Navigation with Interacting, Non-Communicating Obstacles
This talk addresses navigation in an environment occupied by other interacting agents (e.g. vehicles, robots, pedestrians…) with no direct communication to one another. In contrast to the path planning problem, the difficulty here is that agents cooperate and compete, creating feedback loops each only partially controls. The talk starts with a very high level overview of two control design methods: Model Predictive Control (MPC) and Control Barrier Functions (CBF). The MPC is powerful, yet computationally expensive. The CBF approach is computationally simpler and handles non-convex constraints gracefully, while, being recently introduced, is only partially understood. Performance of a CBF controller is illustrated with a real industrial robot avoiding a stationary cone. The problem with interacting, non-communicating agents is much more difficult than avoiding stationary objects. Each agent has only a portion of the information needed to find the optimal or even a feasible action. Another difficulty is that, unless other agents are treated as non-interacting, the computational burden grows quickly with the number of agents. Additionally, this talk reviews these approaches: CBFs, Mixed Integer Programming, and Reinforcement Learning. In simulations, a CBF-based approach developed in-house showed good performance in avoiding collisions, not only when all the agents are implementing the same algorithm, but also when an agent becomes non-interacting or is even actively pursuing another agent. The computational load remains reasonable with each agent, as the host is able to handle up to about 20-25 interacting targets on a 3GHz computer.

Learning MPC in Autonomous Systems
Forecasts play an increasingly important role in the next generation of autonomous and semi-autonomous systems. Applications include transportation, energy, manufacturing and healthcare systems. Predictions of systems dynamics, human behavior and environment conditions can improve safety and performance of the resulting system. However, constraint satisfaction, performance guarantees and real-time computation are challenged by the growing complexity of the engineered system, the human/machine interaction and the uncertainty of the environment where the system operates. Our research over the past years has focused on predictive control design for autonomous systems performing iterative tasks. In this talk I will first provide an overview of the theory and tools that we have developed for the systematic design of learning predictive controllers. Then, I will focus on recent results on the use of data to efficiently formulate stochastic MPC problems which autonomously improve performance in iterative tasks. Throughout the talk I will focus on autonomous cars to motivate our research and show the benefits of the proposed techniques.

Network Monitoring of Industrial Control Systems: The Lessons of Security Matters.
Established in 2009 in the Netherlands as a University spin-off by a Professor and two PhD students, SecurityMatters was acquired in 2018 by the American ForeScout Technologies Inc. (NASDAQ:FCST). SecurityMatters pioneered a new way of realizing network monitoring for cybersecurity that proved very successful in the Critical Infrastructure domain (Oil and Gas, Power Generation, Energy Distribution etc.). Besides a success story, SecurityMatters has also represented an enormous learning experience, benchmarking different approaches against reality. In this lecture, one of the founders of SecurityMatters will give his unsweetened opinion regarding what works and what does not work, when it comes to network monitoring.

CITRIS/CPAR and CPSRC Seminar: The Economics of Robotics
This seminar is a review of the latest investments into the robotics industry, and how difficulties in the categorization of the robotics industry in US and overseas hinders awareness of emerging robotics technologies. In 2014, the robotics industry hit two tipping points. One was a huge increase in funding going into new areas of emerging robotics industries, and the other has been the move away from traditional market analytics based on sales figures to predict future growth, towards the much more complex analysis of disruption, market cycles, and effectively trying to read the entrails of the investment industry.
