This paper presents a nonlinear fault-tolerant control (FTC) and sensor fault diagnosis for lawn chairs 9 inches off the ground longitudinal dynamics of hypersonic flight vehicle.A nominal sliding mode control is developed to track the reference command of velocity and altitude on the basis of an affine nonlinear dynamic model.A nonlinear adaptive
The article deals with semantic relations in phraseology in modern English.In particular, the authors attempt to analyze different perspectives on the problem of correlation of concepts such as phraseological variance and synonyms existing in Russian linguistics.In addition, the article reviews and analyzes the nature and mechanism of phraseologica
This paper studies several problems that may exist in the aerodynamic design of low Mach number general aircraft, and lawn chairs 9 inches off the ground discusses the design characteristics of the pressure distribution of some related airfoils while part of the characteristics is verified by a multi-point laminar airfoil design case.Firstly, sever
Wild pigs (Sus scrofa) alter ecosystems, affect the economy, and carry diseases that can be transmitted to livestock, humans, and wildlife.Understanding wild pig movements and population structure data, including natural population boundaries and dispersal, may potentially increase the efficiency and effectiveness of management actions.We blueberry
