Neural Network Adaptive Control With Long Short‐Term Memory

International Journal of Adaptive Control and Signal Processing, EarlyView.
ABSTRACT In this study, we propose a novel adaptive control architecture that provides dramatically better transient response performance compared to conventional adaptive control methods. This is accomplished by the synergistic employment of a traditional adaptive neural network (ANN) controller and a long short‐term memory (LSTM) network.

Relativistic stars in differential rotation: bounds on the dragging rate and on the rotational energy

, 2003
For general relativistic equilibrium stellar models (stationary axisymmetric asymptotically flat and convection-free) with differential rotation, it is shown that for a wide class of rotation laws the distribution of angular velocity of the fluid has a ...

Numerical Studies of Influencing Factors on the Homogeneity of the Powder Mixture during the Powder Spreading Process of Powder Bed Fusion–Laser Beam/Metal

Advanced Engineering Materials, EarlyView.
AISI 304L stainless steel powder is mixed with silicon nitride (Si3N4) powder and processed by PBF‐LB/M, allowing partial retention of Si3N4. The numerical approach effectively predicts the Si3N4 powder homogeneity and N content distribution on the powder bed. Recent studies have focused on the alloying of nitrogen (N) in high‐alloy stainless steels by

Rotation and twist regular modes for trapped ghosts

, 2012
A parameter-independent notion of stationary slow motion is formulated then applied to the case of stationary rotation of massless trapped ghosts. The excitations correspond to a rotation mode with angular momentum $J\neq 0$ and twist modes.

Regulation of the downside angular velocity of a drilling string with a P-I controller

European Control Conference, 2018
In this paper, we demonstrate that a simple Proportional-Integral (P-I) controller allows to regulate the angular velocity of a drill-string despite unknown friction torque and by only using measurement of angular velocity at the surface. Our model is an

Bridging Nature and Technology: A Perspective on Role of Machine Learning in Bioinspired Ceramics

Advanced Engineering Materials, EarlyView.
Machine learning (ML) is revolutionizing the development of bioinspired ceramics. This article investigates how ML can be used to design new ceramic materials with exceptional performance, inspired by the structures found in nature. The research highlights how ML can predict material properties, optimize designs, and create advanced models to unlock a ...

Study on the mechanism of railway vehicle wheelset angular velocity change on curved tracks

Nihon Kikai Gakkai ronbunshu
The moving block system provided by CBTC increases train operation frequency and improves facilities management efficiency compared to the fixed block system. Trains controlled by CBTC need to have onboard functions to estimate their locations.

Control of the rolling of a dynamically symmetrical sphere on an inclined rotating plane [PDF]

Известия Саратовского университета. Новая серия. Серия Математика. Механика. Информатика
The work investigates the rolling dynamics of a dynamically symmetrical heavy sphere (or a heavy spherical shell) along an inclined rough plane (platform) rotating with constant or periodic angular velocity around an axis, which is perpendicular to the ...
