In this article, five feedback magnetic attitude control algorithms are compared in terms of stabilization accuracy and implementation problems. The control strategies are classic Lyapunov control with scalar gain; the same control strategy with matrix g...

A first aim of the present work is the determination of the actual sources of the ?finite precision error? generation and accumulation in two important algorithms: Bernoulli?s map and the folded Baker?s map. These two computational schemes attract the at...

To improve the tracking stability control of unmanned surface vehicles (USVs), an intelligent control algorithm was proposed on the basis of an optimized radial basis function (RBF) neural network. The design process was as follows. First, the adaptation...

We focus on the problem of adding fault-tolerance to an existing concurrent protocol in the presence of unchangeable environment actions. Such unchangeable actions occur in cases where a subset of components/processes cannot be modified since they repres...

The subject of this work is the implementation and experimental testing of a purely magnetic attitude control strategy, which can provide stabilization after the deployment and pointing of the spacecraft without any attitude information. In particular, t...
