The distributed tracking problem is investigated for a class of multi-agent systems with high-order stochastic nonlinear dynamics where the subsystem of each agent is driven by inherent nonlinear drift and diffusion terms. For the case where the graph topology is directed and the leader is the neighbor of only a small portion of followers, a new distributed integrator backstepping design method...

Multipath interference in cities has always been one of the main problems leading to abnormal positioning results a global navigation satellite system. Vector tracking is superior conventional scalar ability mitigating multipath interference. However, due special sharing structure, fault propagation which easily occurs vector loop leads false alarms normal signals during detection. To solve thi...

In this paper, a simple structure design with arbitrary motion/force scaling to control teleoperation systems, with model mismatches is presented. The goal of this paper is to achieve transparency in presence of uncertainties. The master–slave systems are approximated by linear dynamic models with perturbed parameters, which is called the model mismatch. Moreover, the time delay in communicatio...

Use of loop aiding for facilitating the operation of GPS receivers in weak SNIR environments has been widely researched in recent years. Locata, a terrestrial radio navigation system working on similar principles as GPS, can also make use of loop aiding techniques with some additional advantages. Locata employs dual-frequency and dual-antenna transceivers (LocataLites) allowing a Locata rover r...

We evaluate the performance of two control architectures applied to atomic force microscopes (AFM). Feedback-only control is a natural solution and has been applied widely. Expanding on that, combining feedback controllers with plant-injection feedforward filters has been shown to greatly improve tracking performance in AFMs. Alternatively, performance can also be improved by the use of a close...
