WP2. Safety and Reliability

Ali ZOLGHADRI, IMS

The work in this work package will be focused on a single task, designed by T2.1 and entitled  Safety and reliability of distributed engineered systems. The main objective is to develop new modelling tools, design methods and scalable algorithms for monitoring, fault-tolerant control, safety verification and reliability of distributed and large-scale engineered systems. WP2 will address the reliability of distributed networked systems characterized by integrated computational, networking and physical capabilities, their ability to sense and interact with their environment and to generate and process control data which can be communicated and exchanged via their network. Such engineered systems (Cyber Physical Systems) are a key enabler to sustain the growth in future technological developments (aerospace and automotive systems, energy distribution, manufacturing, distributed robotics, medical devices…). In the USA, research on CPS has been placed at the top of the priority list for federal research investment. Since 2010, the European research and industrial community has focused on CPS as paradigms for the future of systems.

The high-level objective of this research initiative is to initiate foundational, original research on monitoring and control of complex distributed systems at the Bordeaux University by converging established expertise from computer science (LaBRI) and from electrical engineering and control (IMS). A tight inter-disciplinary collaboration between the LaBRI and IMS is a unique opportunity to develop this kind of research in Bordeaux and to foster future industrial transfer.

To exploit this potential, we will first develop appropriate modelling tools associating paradigms from control theory and computer science. The aim is first to establish theoretical foundations for development of layered architectures for networked, distributed and hybrid control that can capture both continuous and discrete dynamics. This will enable model-based monitoring and fault-tolerant distributed control for reliable deployment of a large number of advanced distributed control systems on shared, distributed and heterogeneous platforms. Modeling will be a big challenge as it should represent both computing resources and physical processes, and their behavioral interactions. The main challenge is to have a tighter coupling between the physical and the networking layers which can be further exploited to investigate model-based fault monitoring, fault tolerance and fault management and recovery issues. These problems are complex tasks, since they depend on the deployment of sensors in the system and are thus related to the design of the architecture and its optimization. One of the biggest challenges is the curse of dimensionality, and to avoid the complexity obstruction. The scientific issues investigated in this work package cover mainly the first 2 levels on the Technology Readiness Level (TRL) scale. It is foreseen to interact with WP7 activities (robotic and UAV) for implementation and validation of techniques developed, which corresponds partly to TRL3 (experimental proof of concept). This work package will interact also with WP1 activities on autonomous systems.
