Abstract :
In this paper, we present an approach for QoS management that can be applied to a general class of real-time distributed computation systems. In the proposed approach, a switching hybrid system model is used to represent the system. In this setting, the QoS specifications are transformed into set-point specifications and a limited-horizon online supervisory controller is used to move the system to the optimal operation point.
