Abstract : In this thesis, we study a coordinated approach for the design of control laws and scheduling parameters. The first objective is to propose and evaluate a technique to control the degradation of the quality of control (QoC) by selectively rejecting task or message instances according to the (m,k)-firm model. More specifically, we have studied the impact of the (m,k)-firm packet dropout policy on the QoC of a control loop. Based on the obtained results, we have specified a co-design method for determining the parameters (gain) of the optimal control
law and the (m,k)-firm constraint specifying the selective rejet of instances. This proposal was validated by using analytical techniques, simulation and experimentation activities.
The second objective is to address the scheduling problem of a set of real-time tasks where each task implements a control law in a centralized scalable application. We proposed a scheduling mechanism which determines on line, according to the current system configuration, a (m,k)-constraint based scheduling strategy to apply to each task so that the criterion reflecting the overall performance of the application is optimal at all times.
