Friction compensation of servo system based on terminal switching function
The Journal of Engineering, 2013 Based on the LuGre friction model, a sliding mode adaptive controller is presented to compensate for the friction in the servo system. The terminal switching function is selected as the sliding mode surface, which can make the error of the system ...

Multi-Scroll Attractor and Multi-Stable Dynamics of a Three-Dimensional Jerk System
Energies, 2023 A multi-scroll attractor reflects the structural diversity of the dynamic system, and multi-stability behavior reflects its state diversity. Multi-scroll and multi-stability chaotic systems can produce complex random sequences, which have important ...

Rumor Spreading Model Considering Individual Activity and Refutation Mechanism Simultaneously
IEEE Access, 2020 With the rapid development of social networks, an increasing number of factors will affect the spread of rumors. In this paper, we simultaneously consider individual activity differences and rumor-refuting nodes, and we propose a new multifactor model ...

Approximate Equilibrium Problems and Fixed Points [PDF]
International Journal of Analysis, 2013 We find a common element of the set of fixed points of a map and the set of solutions of an approximate equilibrium problem in a Hilbert space. Then, we show that one of the sequences weakly converges. Also we obtain some theorems about equilibrium problems and fixed points.

Equilibrium points in n -person games [PDF]
Proceedings of the National Academy of Sciences, 1950 Soit un jeu à de \(n\) personnes, où chaque joueur possède un systeme fini de stratégies pures. Chacun d'entre eux ayant choisi une tactique de jeu, l'ensemble de ces tactiques constitute un \(n\)-uple de stratégies pures. A tout \(n\)-uple correspond un système défini de paiement entre les partenaires. L'A. considère chacun de ces \(n\)-uples comme un
