Nonlinear Control of Rotating Flexible Structures Considering Aerodynamic Effects and Non-ideal Inteinteracting with a surrounding quiescent fluid is investigated here. The flexible structure is mathematically modeled considering linear curvature and clamped-free boundary conditions. This structure has an angle of attack which is considered constant in this work. Nonlinearities resulting from the

A Study of the Sommerfeld Effect in a Rotor Machine Foundation Model with 4 DOFat describes the system’s motion is derived via Lagrange’s equations. The solution of this system of differential equations can in principle be carried out analytically, but this can be difficult or even impossible in some cases, particularly when these equations are nonlinear, such as the proposed

Three Kinds of Sommerfeld Effect in Rotor Dynamicshe rotor shaft and disc are perfectly balanced. One of those is related to high amplitude transverse asynchronous whirl of the non-circular rotor shaft due to parametric instability. The other is related to resonance capture in torsional vibrations of the transmission shaft in a universal joint driv

Nonlinear Control of Rotating Flexible Structures Considering Aerodynamic Effects and Non-ideal Inteent (DC) motor, responsible for the angular displacement, interacts with the structure being moved and this structure interacts with the DC motor, characterizing what is conventionally called a non-ideal system. It is one of the objectives of this research to investigate the degree of this interacti

Here, the physical parameters of the structure enable to present the phase and anti-phase or rapid and late synchronization phenomena between the motors.
