Co-Design of Responsive Real-Time Control Sontrol Systems

Quality-aware Co-Design of Responsive Real-Time Control Systems 09/01/2015 - 09/30/2021 Peter Ulbrich Safety-critical control systems must comply with a specific quality of control. However, the relationship [...] degraded by varying execution conditions of the underlying real-time system. This is particularly relevant for modern, adaptive real-time systems, which introduce varying timing conditions for the sake of efficiency [...] research objective of qronOS is the avoidance of pessimism in the design of hard real-time control systems and thus to abandon the trade-off between quality-of-control guarantees and good average performance …
