Abstract: Abstract In this paper, we study the worst rate of exponential decay for degenerate gradient flows in ℝn of the form ẋ(t) = —c(t)c(t)Tx(t), issued from adaptative control theory, under a persistent excitation (PE) condition.… read more here.

DOI: 10.1109/access.2020.3015593
Abstract: Intelligent unmanned aerial vehicles (UAVs) have been applied for civil and military uses. Relative localization (RL) is crucial for multi-UAVs to accomplish complex tasks successfully and safely. In global positioning system (GPS) denied environments, where… read more here.
