| Research Abstract |
We proposed management methods of control tasks which are adaptive to the current environment optimally in cyber-physical systems. Using an elastic task model, we formulated a trade-off between the energy reduction in real-time computing systems and the improvement of control performances as an optimization problem. Then, we obtained an algorithm for computing its optimal solution. Next, we proposed two methods to avoid overload situations using a multi-version task model and job skipping. Finally, we designed a control task to search an optimal position on-line in a multi-agent system where each agent works cooperatively.
