On the applicability of linear feedback for nonlinear systems in fluid mechanics

Proceedings of the 1999 American Control Conference (Cat. No. 99CH36251), 1999
Examines the application of linear optimal control theory to a low-order nonlinear chaotic convection problem. Linear control feedback is found to be fully effective only when it is switched off while the state is far from the desired equilibrium point, relying on the attractor of the system to bring the state into a neighborhood of the equilibrium ...

Stability and tracking performance of dynamic visual feedback control for nonlinear mechanical systems

Proceedings of the 40th IEEE Conference on Decision and Control (Cat. No.01CH37228), 2002
This paper investigates a robot motion control problem with visual information. First, the model of the relative rigid body motion and the nonlinear observer are shown in order to derive the visual feedback system. Next, a design algorithm for the 3D visual feedback control problem which contains the manipulator dynamics are considered.

A nonlinear feedback model for the mechanical response of outer-hair-cell sterocilia

The Journal of the Acoustical Society of America, 1982
There is some experimental evidence that the mechanical cochlear function is strongly influenced by the efferent innervation of outer-hair-cell stereocilia (OHCS). [See, e.g., D. C. Mountain, Science 210, 71–72 (1980); J. H. Siegel and D. O. Kim, Hear. Res.

Modal self-excitation in a class of mechanical systems by nonlinear displacement feedback

Journal of Vibration and Control, 2016
Many devices and processes utilize self-excited oscillation to enhance performance. Recently, much research work has been devoted to the induction of self-excited oscillation in mechanical systems by nonlinear feedback. The present paper investigates the efficacy of a displacement feedback technique in generating self-excited oscillation at the desired

Linear Feedback Control of Position and Contact Force for a Nonlinear Constrained Mechanism

Journal of Dynamic Systems, Measurement, and Control, 1990
A feedback control problem for a constrained mechanism is formulated and solved. The mechanism is controlled by forces applied to the mechanism which are to be adjusted according to a linear control law, based on feedback of the positions and velocities of the mechanism and feedback of the constraint force on the mechanism.

Modal self-excitation by nonlinear acceleration feedback in a class of mechanical systems

Journal of Sound and Vibration, 2016
Abstract The article proposes an acceleration feedback based technique for exciting modal self-oscillation in a class of multi degrees-of-freedom mechanical systems. The controller comprises a bank of second-order filters and the control law is formulated as the nonlinear function of the filter output. A design methodology is developed to excite self-

Using nonlinear feedback control to model human landing mechanics

2018
Human beings interact with a variety of terrains on a regular basis, adapting their joint coordination strategies to account for these diverse mechanical conditions. Because these adaptive processes are always engaged, they play an integral role in driving the dynamics of the body.

The quantum-mechanical two-level system with dissipation and feedback: application to nonlinear dielectric response

Canadian Journal of Physics, 1986
A power-series expansion for long-time solutions is obtained for the density-matrix equations of motion describing a quantum-mechanical two-level system with dissipation and feedback. The resonances in the first- and third-order dipole contributions and the second-order upper level occupation probability are shown to be significantly affected by the ...
