For real-time computer-controlled systems, control performances of tasks as well as energy consumption of overall system must be optimized. A control task does not have a fixed period but a range of periods in which control performance varies. Hence when more than one control tasks are scheduled on a single processor, an optimization problem appears.(More)
The Dynamic Voltage Scaling (DVS) technique has been widely studied for energy-constrained real-time systems; however, its application to control systems has not been studied in a variety of aspects. This article presents a novel method to simultaneously schedule processor voltage and control-task periods online, considering energy-efficiency of control(More)
