Aircraft adaptive learning control [PDF]

open access: yes
The optimal control theory of stochastic linear systems is discussed in terms of the advantages of distributed-control systems, and the control of randomly-sampled systems.

Configurational and system requirements for control of large space systems [PDF]

open access: yes, 1982
Control of large space systems, modeling, and control difficulties are discussed. Ground based analysis of spaceflight data are presented to determine structural dynamics characteristics for the purpose of revising control laws, and to trim the surface ...

Adaptive position control loop [PDF]

open access: yes, 1972
Design of attitude control system for a sounding rocket is established by using a control loop which incorporates a lead network to convert position output into a feedback signal that is approximately proportional to position, plus a constant times ...

Joint-space adaptive control of a 6 DOF end-effector with closed-kinematic chain mechanism [PDF]

open access: yes
The development is presented for a joint-space adaptive scheme that controls the joint position of a six-degree-of-freedom (DOF) robot end-effector performing fine and precise motion within a very limited workspace.

Adaptive Networks Safety Control

open access: yesAdvances in Electrical and Computer Engineering, 2007
In this paper we suggest a new approach to design of the adaptive network safety control mechanisms. This approach is based on the fuzzy logic theory and allows to formalize both quantitative and qualitative parameters of the network safety system.

An adaptive optimisation scheme for controlling air flow process with satisfactory transient performance [PDF]

open access: yesMaejo International Journal of Science and Technology, 2010
A non-identifier-based adaptive PI controller is designed using a gradient approach to improve the performance of a control system when device aging and environmental factors degrade the efficiency of the process.

A decade of change: maternal mortality trends in Sudan, 2009–2019

open access: yesBMC Public Health
Background Unacceptably high levels of preventable maternal deaths persist across sub-Saharan Africa. Due to limited research on maternal mortality in Sudan, a thorough examination is crucial to develop effective reduction strategies.

Estimate Laplacian Spectral Properties of Large-Scale Networks by Random Walks and Graph Transformation

open access: yesMathematics
For network graphs, numerous graph features are intimately linked to eigenvalues of the Laplacian matrix, such as connectivity and diameter. Thus, it is very important to solve eigenvalues of the Laplacian matrix for graphs.

Unknown system dynamics estimator based control for sub‐synchronous oscillation of direct‐drive wind farms

open access: yesIET Control Theory & Applications
Aiming at the problem of sub‐synchronous oscillations induced by direct‐drive wind farms with series‐compensated lines, this paper proposes an unknown system dynamics estimation‐based PI controller to achieve sub‐synchronous oscillation suppression ...
