Delay Tolerant Networks are a type of challenging, uninterrupted network in which there is not an end-to-end path between the source and the destination. These networks play a key role in managing crises in natural disasters such as earthquakes, fire

Higher transistor density in modern processors leads to an increase in computing power, which results in higher power consumption. To combat this, system-level power saving features like dynamic voltage transitions (DVTs) are introduced where the vol

Inductor DC resistance (DCR) measurement is the standard technique used to measure the current in a single- or multi-phase voltage regulators in computing applications. It is well noted that variations in operating conditions such as temperature caus

This paper addresses the problem of time-optimal load-transient response in digitally controlled dc-dc buck converters incorporating an inductor current limitation. The concept of current-limited, time-optimal control (CL-TOC) is introduced and compa

This paper presents a hybrid digital adaptive (HDA) control for fast step-load transient responses in synchronous buck DC-DC converters. The proposed HDA controller results in near-time-optimal step-load transient responses even when the output volta

In this paper, a new approach for optimal control of robot manipulators is presented. For this purpose, the system is considered as a two-level large-scale system where a gradient-based coordination strategy is used to coordinate the overall system.

Optimal control frameworks are very important in optimization of multiple-arm robotic systems, although complexity, non-linearity and having large scales usually cause some computational problems in the capacity and time needed. In this paper, it is

This paper analyzes the general problem of inductor current limitation in the time-optimal load transient response of a DC-DC buck converter. The concept of current-limited, time-optimal control (CL-TOC) is introduced and compared to the previously r
