In this article, vibration characteristics and the parametric instability of functionally graded material (FGM) plates with cyclic loading in a hygrothermal field are discussed. The plate element is modeled in a finite element by applying the third-order shear deformation hypothesis. The mathematical formulation of the FGM plate is made with two material constituents by applying the power rule ...

In this article, control oriented uncertainty modeling of an uncommon quadrotor in hover is discussed. This consists two counter-rotating big rotors on longitudinal axis and small tilt lateral axis. Firstly, approximate linear model vehicle around obtained by using Newton--Euler formulation. Secondly, specific assigned to each parameter. Resulting uncertain converted into a fractional transform...
