High performance control design for dynamic voltage scaling devices

Abstract

Dynamic Voltage Scaling (DVS) is an important method in managing dynamically the system supply voltage for efficient power reduction. This approach is applied in Very-Large-Scale Integration (VLSI). A DC-DC converter is an electronic device which allows to vary the voltage and, thus, to implement DVS technique. In this paper, a high-performance controller is presented for a novel discrete DVS converter. This controller is developed with the aim to deal with the unknown resistive component of the load as well asto minimize the dissipated energy and current peaks, what is very important in the field of microelectronics. Current peaks and power consumption are minimized by computing an optimal evolution for the voltage reference. Likewise, an adaptive controller is proposed to deal with the unknown load resistive parameter. Consequently, the obtained advanced controller can acquires a high consideration on electronic devices.
