“Cyberphysical Security of Critical Infrastructures ” - Prof. Vicenç PUIG
Universitat Politècnica de Catalunya · BarcelonaTech (UPC) - Spain
The secure operation of critical infrastructures is a growing concern with the advent of cyberphysical systems paradigm that leads to the interconnection of the digital and physical worlds. The increase of system connectivity with the the use of new communication facilities have an important number of potential benefits. However, new problems that before were not considered as the increasing vulnerability to attacks as confirmed by the rise of cybersecurity incidents in several critical infrastructures worldwide. This fact has recently motivated in the research community a growing interested in developing methods for the detecting attacks in cyberphysical systems and their reconfiguration to preserve the secure operation.
This talk will introduce the problem of cyberphysical security and some possible approaches in the context of critical infrastructures. This type of cyberphysical systems has specific particularities as the networked structure, the large size and complexity of already deployed automatic control systems. For illustrating the proposed approaches, real case studies based on water networks will used along the presentation. The talk will end presenting some discussion about possible future developments and about the cooperation between the FDI and cybersecurity communities
“Dealing with uncertainty in learning-based control and optimization: the Set membership paradigm ”
Dr. Lorenzo FAGIANO - Politecnico di Milano · Milan - Italy
Most engineering problems can be cast as follows: given prior information and data (models, requirements, experimental data, etc.), estimate or "learn" a vector of parameters (model parameters, system design parameters, controller parameters, etc.) that are optimal according to a suitably defined criterion. The most common approaches to deal with this problem return one parameter vector ("model first"). Quantifying the related uncertainty or robustness is often challenging : yet, in safety-critical applications the uncertainty associated with a solution can be more important than the solution itself. Set Membership methods are a family of approaches designed to compute an uncertainty estimate ("uncertainty first") in the form of a set of admissible parameters, rather than returning a single point. Thus, they provide a systematic way to associate uncertainty to a given parameter vector and to choose, for example, the parameters that minimize uncertainty. The talk will briefly review the main concepts of Set Membership methods and focus on two specific techniques: the design of adaptive model predictive controllers and the global, derivative-free solution of black-box optimization problems, where both the cost and the constraint functions are not tractable analytically.
“Damage compensation in robotics without diagnosis” - Dr. Jean-Baptiste MOURET
INRIA · Nancy - France
Robots are complex and fragile machine that easily stop working in difficult conditions. To be deployed outside of labs and the manufacturing industry, they need to cope with unexpected damage. During the last 6 years, we developped a family of algorithms that exploit data-efficient trial-and-error learning (reinforcement learning) to find compensatory behaviors without any explicit diagnosis. For instance, they allow a 6-legged robot with a broken leg to discover new gaits in less than 2 minutes (a dozen of trials), or a humanoid robot to avoid failing when a motor in the leg is disconnected.
