Abstract : During the design of a computer controlled system, there is a traditional separation of concern between control law and scheduling design. In embedded systems, with limited and varying resources, this separation leads to under utilization of the processor. To improve the control/scheduling interactions we propose to adapt the resources usage of the control law computations by adjusting their sampling period. Some preliminary results concern the design of a feedback scheduling using a robust control approach. The main result of this work is the development of a control synthesis methodology with variable sampling period using the Hinfinity approach for linear varying parameter systems. The performance of the control law and its interaction with the scheduling are illustrated in simulation and by experimental results.
