In this work, a prescribed-time second-order sliding mode (SOSM) controller is constructed to address class of nonlinear systems in the presence asymmetric output constraints. To handle constraints, frequently-used barrier Lyapunov function employed. Meanwhile, time-varying scaling introduced ensure convergence closed-loop system. On basis, SOSM by inserting BLF and into modified power integrat...

In order to simultaneously address the issues of ship operating area limitation, unknown time-varying disturbances, immeasurable speed, dynamics, and input saturation, this paper investigates position-constrained dynamic positioning output feedback control, taking thruster system dynamics into account. Firstly, a barrier Lyapunov function (BLF) is utilized limit position inside system’s accepta...

Across southern China, Moso bamboo has been encroaching on most neighboring secondary broad-leaved forests and/or coniferous plantations, leading to the land cover changes that alter abiotic and biotic conditions. Little is known about how this conversion alters soil carbon (C) and nitrogen (N). We selected three sites, each with three plots arrayed along the bamboo encroachment pathway: moso b...

This article concentrates on the event-driven controller design problem for a class of nonlinear single input output parametric systems with full state constraints. A varying threshold triggering mechanism is exploited, which makes communication more flexible. Moreover, from viewpoint energy conservation and consumption reduction, system capability becomes better owing to contribution proposed ...

The La modified bismuth ferrite perovskite Bi0.6La0.4FeO3 (BLF) is prepared by cost-effective high solid-solution casting technique. Formation of composite checked through X-ray diffraction and also notable that there phase transition from rhombohedral (R3c) to orthorhombic (Pbnm). average crystalline size (DSC) mechanical lattice strain are 63.8 nm 0.147% respectively as calculated Williamson-...

As a source of biologically active compounds, buckwheat has beneficial effects in nutrition due to its high content of flavonoids, particularly rutin. Aim of our study was to examine effects of buckwheat on plasma lipid status and phospholipids fatty acids composition, histological and parameters of oxidative stress in Wistar rats fed a high-fat diet. This study showed that buckwheat leaf and f...
