On Nonlinear Perturbations of Nonlinear Dynamical Systems, and Applications to Control [PDF]

IMA Journal of Mathematical Control and Information, 1984
The nonlinear variation-of-constants formula is generalized to infinite- dimensional systems and applied to the stability problem and used to obtain bounds on the states of a nonlinear control system when the controls are bounded. The theory is illustrated by a simple model from nuclear reactor dynamics.

Experimental Characterization and Constitutive Modeling of the Effect of Prior Inelastic Strain on the Viscoplastic Behavior of AD730 at 700 °C

Advanced Engineering Materials, EarlyView.
This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

Symmetries, stability, and control in nonlinear systems and networks

, 2011
This paper discusses the interplay of symmetries and stability in the analysis and control of nonlinear dynamical systems and networks. Specifically, it combines standard results on symmetries and equivariance with recent convergence analysis tools based

Influence of Geometric Design on Mechanical Performance of Auxetic Metastructure

Advanced Engineering Materials, EarlyView.
Strategic geometric reinforcement transforms auxetic performance. This study evaluates 3D‐printed arrowhead metastructures, revealing that a modified design with local ring reinforcement suppresses premature failure to achieve superior energy absorption and structural efficiency.

Complexity reduction of Nonlinear Systems

, 2010
A common problem in nonlinear control is the need to consider systems of high complexity. Here we consider systems, which although may be low order, have high complexity due to a complex right hand side of a differential equation (e.g.

Bifurcations of backbone curves for systems of coupled nonlinear two mass oscillator [PDF]

, 2014
This paper considers the dynamic response of coupled, forced and lightly damped nonlinear oscillators with two degree-of-freedom. For these systems, backbone curves define the resonant peaks in the frequency-displacement plane and give valuable ...

Open Set Domain Adaptation for Classification of Dynamical States in Nonlinear Fluid Dynamical Systems

IEEE Access
Nonlinear fluid dynamical systems, such as thermoacoustic systems, aeroelastic systems are archetypical complex systems involving state transitions upon a change in bifurcation parameter.

Integral observability operators of nonlinear dynamical systems

International Journal of Mathematics and Mathematical Sciences, 2003
In terms of functional dependence, the description of observable functions in nonlinear dynamical systems, which are analytic with respect to phase variables, is obtained. For processing of measurements, integral operators are used, which provide certain

Mission Planning and Control of Multi-Aircraft Systems With Signal Temporal Logic Specifications

IEEE Access, 2019
This paper focuses on optimization-based control of multi-aircraft systems that have several mission objectives. Signal Temporal Logic (STL) is used to express the mission specifications that combine temporal and logical constraints.
