Control and Synchronization of Hyperchaotic System based on SDRE Method [PDF]

International Journal of Information Engineering and Electronic Business, 2014
In this paper, stabilization and synchronization problems of the hyperchaotic system is investigated. For this reason, state dependent Riccati equation (SDRE) is used. First, stabilizer is designed by SDRE method. Then, robust controller is designed that it can stabilize hyperchaotic system with uncertainly. Finally, synchronization problem between two

Disarming the Pathogenicity of Methicillin‐Resistant Staphylococcus aureus via Osmundacetone‐Mediated Inhibition of Sortase A

Microbial Biotechnology, Volume 18, Issue 5, May 2025.
OSC inhibits the activity of the surface protein SrtA in S. aureus. SrtA recognises and cleaves the threonine (T) and glycine (G) residues of the LPXTG motif, covalently anchoring surface proteins to the cell wall, which promotes the adhesion and invasion of host cells.

Uncovering a new family of conserved virulence factors that promote the production of host‐damaging outer membrane vesicles in Gram‐negative bacteria

Journal of Extracellular Vesicles, Volume 14, Issue 1, January 2025.
Abstract CprA is a short‐chain dehydrogenase/reductase (SDR) that contributes to resistance against colistin and antimicrobial peptides. The cprA gene is conserved across Pseudomonas aeruginosa clades and its expression is directly regulated by the two‐component system PmrAB.

Maximum Dynamic Load Determination via a Novel Robust State‐Dependent Differential Riccati Equation

IET Control Theory &Applications, Volume 19, Issue 1, January/December 2025.
ABSTRACT This paper presents a novel application of the differential form of the state‐dependent Riccati equation technique (SDRE) i.e., the state‐dependent differential Riccati equation (SDDRE) as an indirect solution to the robust tracking control (RTC) problem for determining maximum dynamic load.

Varying Speed Cooperative Differential Game Guidance Laws With Intercept Angle Constraints

International Journal of Aerospace Engineering, Volume 2025, Issue 1, 2025.
For intercepting modern highly maneuvering targets, considering the velocity variation of adversaries, a varying speed cooperative differential games guidance method is proposed, which can enable multiple air‐to‐air missiles to intercept targets at a predefined relative intercept angle.
