摘要
In this paper, we present a novel robust sliding-mode controller for stabilizing supply voltage and clock frequency of dual core processors determined by dynamic voltage and frequency scaling (DVFS) methods in the presence of systematic and random variations. We show that maximum rejection for process, voltage and temperature (PVT) variations can be achieved by using the proposed sliding-mode controller. The stabilization of the presented controller is confirmed by the Lyapanov method. Experimental results demonstrate maximum 20% robustness against 20% parameter variations for a hardware of two core processors executing a JPEG decoding application.
