In cloud storage centers, replica of file may be lost subjected to the failure of nodes, which will affect the efficiency of file access, as well as users' satisfaction. To cope with this problem, the method of redeploying the lost replicas on some other servers to maintain system availability is often adopted. Normally, a file is divided into many blocks with the same size and the popularity of the...
We consider a set of control tasks that must be executed on distributed platforms so that end-to-end latencies are within deadlines. We investigate how to allocate tasks to nodes, pack signals to messages, allocate messages to buses, and assign priorities to tasks and messages, so that the design is extensible and robust with respect to changes in task requirements. We adopt a notion of extensibility...
A robust model predictive control algorithm is proposed for linear systems with input saturation in this paper. Polytopic uncertain systems and structured time-varying uncertain systems are respectively considered. An infinite horizon worst-case performance function is used as on-line optimization objective. Using a saturated linear feedback controller, the control action can be obtained by solving...
