Spectral Characterization of Anomalous Diffusion of a Periodic Piecewise Linear Intermittent Map

, 2003
For a piecewise linear version of the periodic map with anomalous diffusion, the evolution of statistical averages of a class of observables with respect to piecewise constant initial densities is investigated and generalized eigenfunctions of the ...

Data‐Driven Modeling and High‐Precision Tracking Control of a Soft Continuum Manipulator: Enabling Robotic Sorting of Multiwire Cables

Advanced Intelligent Systems, Volume 6, Issue 10, October 2024.
Sorting multiwire cables is a common task in manufacturing. Motivated by this industrial application, a hybrid offline and online data‐driven scheme is proposed to achieve high‐precision tracking control of a soft continuum manipulator, enabling cable sorting automation.

Optimal excitation of two dimensional Holmboe instabilities

, 2011
Highly stratified shear layers are rendered unstable even at high stratifications by Holmboe instabilities when the density stratification is concentrated in a small region of the shear layer.

Learning Lyapunov Functions for Piecewise Affine Systems with Neural Network Controllers [PDF]

arXiv, 2020
We propose a learning-based method for Lyapunov stability analysis of piecewise affine dynamical systems in feedback with piecewise affine neural network controllers. The proposed method consists of an iterative interaction between a learner and a verifier, where in each iteration, the learner uses a collection of samples of the closed-loop system to ...

A review of control strategies for optimized microgrid operations

IET Renewable Power Generation, Volume 18, Issue 14, Page 2785-2818, 26 October 2024.
Microgrids (MGs) are gaining traction as a sustainable and reliable power solution, particularly in remote areas. Efficient and intelligent control strategies are crucial for optimizing MG operations and maximizing the utilization of distributed energy resources, storage systems, networks, and loads.

Output‐based enhanced closed‐loop model reference adaptive control and its application to direct yaw moment control

International Journal of Robust and Nonlinear Control, Volume 34, Issue 14, Page 9471-9500, 25 September 2024.
Abstract The enhanced model reference adaptive control (EMRAC) algorithm is an effective full‐state adaptive solution to control plants affected by nonlinear unmodelled dynamics and persistent disturbances. The EMRAC strategy improves the tracking performance by equipping the MRAC algorithm with adaptive switching and adaptive integral control actions.

Stirring, stretching and transport generated by a pair of like-signed vortices [PDF]

, 2011
We consider a pair of like-signed, initially elliptical vortices with uniform vorticity distribution embedded in an incompressible, inviscid fluid occupying a two-dimensional, infinite domain. We characterize this finite-time, aperiodic, dynamical system

Virtual control contraction metrics: Convex nonlinear feedback design via behavioral embedding

International Journal of Robust and Nonlinear Control, Volume 34, Issue 12, Page 7698-7721, August 2024.
Abstract This article presents a systematic approach to nonlinear state‐feedback control design that has three main advantages: (i) it ensures exponential stability and ℒ2$$ {\mathcal{L}}_2 $$‐gain performance with respect to a user‐defined set of reference trajectories, (ii) it provides constructive conditions based on convex optimization and a path ...

A bit rate condition for feedback stabilization of uncertain switched systems with external disturbances based on event triggering

IET Control Theory &Applications, Volume 18, Issue 9, Page 1136-1151, June 2024.
Abstract This paper studies the input‐to‐state stability of an uncertain switched linear system with external disturbances, whose feedback loop is closed over a digital communication network. In the network, only a finite bit rate can be provided to transmit the feedback signal and unknown network delay always exists.
