EUCON

The End-to-end Utilization CONtrol (EUCON) algorithm features a distributed performance feedback loop that dynamically enforces desired CPU utilization bounds on multiple processors in distributed real-time embedded systems. EUCON is based on a novel model predictive control approach that models the utilization control problem on a distributed platform as a multi-variable constrained optimization problem. A multi-input-multi-output model predictive controller is designed and analyzed based on a difference equation model of distributed real-time systems.
