Global Stability Analysis of Mechanical Prosthetic Finger Adaptive Control [PDF]

open access: yesRevista Română de Informatică și Automatică, 2022
This technical note presents a discussion on the dynamic modeling and analysis of the adaptive controller of a Mechanical Prosthetic finger with constraints mass (m) of the mechanical finger and constant friction (K1) with variation in spring constraint (

Observability of fidelity decay at the Lyapunov rate in few-qubit quantum simulations [PDF]

open access: yesQuantum, 2022
In certain regimes, the fidelity of quantum states will decay at a rate set by the classical Lyapunov exponent. This serves both as one of the most important examples of the quantum-classical correspondence principle and as an accurate test for the ...

Stability Analysis of Switched Linear Singular Systems with Unstable and Stable Modes

open access: yesEntropy, 2023
In this paper, stability is studied for a class of switched singular systems containing both stable and unstable modes. By introducing a time-varying piecewise Lyapunov function (TVPLF) and a mode-dependent average dwell time (ADT) switching rule, the ...

Ruling Out Positive Lyapunov Exponents by Using the Jacobian’s Second Additive Compound Matrix

open access: yesIEEE Control Systems Letters, 2022
Second additive compound matrices of the system’s Jacobian are used to formulate sufficient conditions to rule out existence of attractors with positive Lyapunov exponents. The criteria are expressed in terms of Lyapunov dissipation inequalities or Linear Matrix Inequalities amenable to analytic verification.

Frequency Containment Control of Hydropower Plants Using Different Adaptive Methods

open access: yesEnergies, 2021
With the growth in the share of variable renewable energy sources, fluctuations in the power generation caused by these types of power plants can diminish the stability and flexibility of the grid.

Stability of Switched Systems with Time-Varying Delays under State-Dependent Switching

open access: yesMathematics, 2022
This paper studies the stability of linear switched systems with time-varying delays and all unstable subsystems. According to the largest region function strategy, the state-dependent switching rule is designed.

Planar mixed flow and chaos: Lyapunov exponents and the conjugate-pairing rule [PDF]

open access: yesThe Journal of Chemical Physics, 2011
In this work we characterize the chaotic properties of atomic fluids subjected to planar mixed flow, which is a linear combination of planar shear and elongational flows, in a constant temperature thermodynamic ensemble. With the use of a recently developed nonequilibrium molecular dynamics algorithm, compatible and reproducible periodic boundary ...

Reference design and comparative analysis of model reference adaptive control for steam turbine speed control [PDF]

open access: yesFME Transactions, 2020
This paper presents the mathematical modeling of the steam turbine unit with the fuzzy controller in an isolated operating condition, especially in nuclear power plants. The water level in the steam generator is one of the main causes for the shutdown of

Análisis de estabilidad de controladores borrosos tipo Mamdani mediante el cálculo del exponente de Lyapunov

open access: yesRevista Iberoamericana de Automática e Informática Industrial RIAI, 2015
Resumen: Determinar la estabilidad de los controladores, ya sea mediante simulaciones o mediante técnicas analíticas, es vital en su diseño e implantación. El método analítico de estabilidad en el sentido de Lyapunov requiere encontrar una función
