State Space Disturbance Observer Considering Residual Disturbance

IEEE Access, 2020
This paper presents a novel disturbance observer (DOB) for overcoming the limitation of uniformly bounded stability in existing DOB-based control systems and to attain asymptotic stability.

Stabilizing Quantum States by Constructive Design of Open Quantum Dynamics

, 2010
Based on recent work on the asymptotic behavior of controlled quantum Markovian dynamics, we show that any generic quantum state can be stabilized by devising constructively a simple Lindblad-GKS generator that can achieve global asymptotic stability at ...

Asymptotic Stability of Time-Varying Nonlinear Cascade Systems with Delay via Lyapunov–Razumikhin Approach

Mathematics
This paper addresses nonlinear time-varying cascade systems governed by differential equations with finite delay. Several sufficient conditions for asymptotic stability are derived, based on differing assumptions regarding the isolated subsystems and ...

Resonance bifurcations from robust homoclinic cycles

, 2009
We present two calculations for a class of robust homoclinic cycles with symmetry Z_n x Z_2^n, for which the sufficient conditions for asymptotic stability given by Krupa and Melbourne are not optimal.

Does stability of relativistic dissipative fluid dynamics imply causality?

, 2010
We investigate the causality and stability of relativistic dissipative fluid dynamics in the absence of conserved charges. We perform a linear stability analysis in the rest frame of the fluid and find that the equations of relativistic dissipative fluid

Asymptotic stability of switching systems

Electronic Journal of Differential Equations, 2010
In this article, we study the uniform asymptotic stability of the switched system $u'=f_{ u(t)}(u)$, $uin mathbb{R}^n$, where $ u:mathbb{R}_{+}o {1,2,dots,m}$ is an arbitrary piecewise constant function. We find criteria for the asymptotic stability

Specific duality and stability of positive electrical circuits

Archives of Electrical Engineering, 2017
The specific duality and asymptotic stability of the positive linear electrical circuits are addressed. The specific duality of positive linear electrical circuits composed of resistances, inductances, capacitances and source voltages is established.

Bayesian estimation of one-parameter qubit gates

, 2008
We address estimation of one-parameter unitary gates for qubit systems and seek for optimal probes and measurements. Single- and two-qubit probes are analyzed in details focusing on precision and stability of the estimation procedure.

Asymptotic stability for second-order differential equations with complex coefficients

Electronic Journal of Differential Equations, 2004
We prove asymptotical stability and instability results for a general second-order differential equations with complex-valued functions as coefficients. To prove asymptotic stability of linear second-order differential equations, we use the technique of ...

Dynamics of a class of uncertain nonlinear systems under flow-invariance constraints

International Journal of Mathematics and Mathematical Sciences, 2003
For a class of uncertain nonlinear systems (UNSs), the flow-invariance of a time-dependent rectangular set (TDRS) defines individual constraints for each component of the state-space trajectories.
