Modal self-excitation by nonlinear acceleration feedback in a class of mechanical systems
Journal of Sound and Vibration, 2016Abstract 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-

ISA Transactions, 2014
This paper presents the formulation of a novel block-backstepping based control algorithm to address the stabilization problem for a generalized nonlinear underactuated mechanical system. For the convenience of compact design, first, the state model of the underactuated system has been converted into the block-strict feedback form.

Nonlinear state feedback ℋ ∞ -control of mechanical systems under unilateral constraints
IFAC Postprint Volumes IPPV / International Federation of Automatic Control, 2014Abstract The work focuses on the state feedback synthesis of hybrid mechanical systems under unilateral constraints. The problem of robust control of mechanical systems is addressed under unilateral constraints by designing a nonlinear state feedback ** ℋ ∞ -controller developed in the hybrid setting, covering impact phenomena. Performance issues of

Modelling of the thyroid hormone synthesis as a part of nonlinear reaction mechanism with feedback
Computers in Biology and Medicine, 2023The synthesis of thyroid hormones in the hypothalamic-pituitary-thyroid (HPT) axis was studied. For this purpose, a reaction model for HPT axis with stoichiometric relations between the main reaction species was postulated. Using the law of mass action, this model has been transformed into a set of nonlinear ordinary differential equations.

Analysis of a nonlinear cochlear feedback mechanism
The Journal of the Acoustical Society of America, 1983The implications of a nonlinear electromechanical cochlear feedback model [S. Koshigoe, W. Kwok, and A. Tubis, J. Acoust. Soc. Am. Suppl. 1 72, S47 (1982)] are explored. The model is shown to be qualitatively compatible with data on stimulated and spontaneous emissions, combination-tone psychophysics, and changes in cochlear response induced by COCB ...

Nonlinear Feedback Mechanisms Inside a Rectangular Cavity
AIAA Journal, 2014An examination of a rectangular cavity with a length-to-depth ratio of 5.67 was tested at Mach 0.7 and 1.5 with corresponding Reynolds numbers of 6.49×106 and 7.35×106/m, respectively. High-speed shadowgraph movies were simultaneously sampled with dynamic pressure sensors at 75 kHz.

AbstractA composite nonlinear feedback (CNF) control with dynamic event‐triggered strategy for saturated systems is considered in this paper. The CNF control is introduced to improve the system response speed and reduce the overshoot under disturbances. The dynamic event‐triggered mechanism (DETM) is utilized to save more communication resources.
