Event-based Wireless Control for Cyber-physical Systems

PIs: Sebastian Trimpe (Max-Planck-Institut für Intelligente Systeme), Marco Zimmerling (TU Dresden)

The next generation of engineered systems will tightly integrate the physical world with computing and communication. These cyber-physical systems (CPS) will exceed present day systems in size, complexity, safety, reliability, and ecological requirements. The EcoCPS project targets the joint design and tight integration of distributed event-based control and low-power wireless networking to demonstrate tangible benefits over traditional isolated designs in terms of, for example, superior performance and robustness, reduced costs, and unprecedented flexibility. To this end, we establish a fundamental understanding and unified description of wireless communication and event-based control and their interrelations so as to develop principled methods for their co-design and tight integration. The methods will take into account the constraints, inter-dependencies, and needs for mutual information exchange between the two systems to optimize system-level performance, while providing theoretical guarantees. Eventually, we aim at a design, where the event-based control system informs the communication system in real-time about its feedback requirements, allowing the wireless network to reconfigure while still guaranteeing end-to-end real-time communication. The benefits of this design will be evaluated on a real-world CPS demonstrator involving unstable, spatially distributed control processes being controlled over a multi-hop low-power wireless network.
