Coordinated Orbit Transfer for Satellite Clusters
We propose a control law which allows a satellite formation to achieveorbit transfer. During the transfer, the formationcan be either maintained or modified to a desired one.Based on the orbit transfer control law proposed ...
Degenerate Gradient Flows: A Comparison Study of Convergence Rate Estimates
Degenerate gradient flows arise in the context of adaptive control of linear systems when the usual gradient algorithm is used for the parameter update law. It is well known that in general parameter convergence is not ...
Cayley Transforms in Micromagnetics
Methods of numerical integration of ordinary differential equations exploiting the Cayley transform arise in a variety of contexts, ranging from the classical mid-point rule to symplectic and (almost) Poisson integrators, ...
Approximate Nonlinear Filtering and Its Applications for GPS
In this paper we address the problem of nonlinear filtering in the presence of integer uncertainty. In the simulation results we show that Particle Filtering is capable of resolving integer ambiguity in the given nonlinear ...
The Berry-Hannay Phase of the Equal-Sided Spring-Jointed Four-Bar Mechanism
In this work we apply the moving systems approach developed by Marsden, Montgomery, and Ratiu to a free-floating, equal-sided, spring-jointed, four-bar mechanism that is being slowly rotated about its central axis and ...
Analysis of a high-resolution optical wave-front control system
We consider the formulation and analysis of a problem of automaticcontrol: correcting for the distortion induced in an optical wave frontdue to propagation through a turbulent atmosphere. It has recentlybeen demonstrated ...
