Adaptive Data-Driven Control for Linear Time Varying Systems
Machines, 2021 In this paper, we propose an adaptive data-driven control approach for linear time varying systems, affected by bounded measurement noise. The plant to be controlled is assumed to be unknown, and no information in regard to its time varying behaviour is ...

Practical stability of time‐varying positive systems with time delay
IET Control Theory & Applications, 2021 This paper considers the problem of practical stability for time‐varying positive systems with time delay. For both non‐linear time‐varying positive systems and linear time‐varying positive (LTVP) systems with time delay, sufficient conditions on ...

A formula for the lower Bohl exponent of discrete time-varying systems [PDF]
Archives of Control Sciences, 2023 In this note, a formula for the lower Bohl exponent of a discrete system with variable coefficients and weak variation was proved. This formula expresses the Bohl exponent through the eigenvalues of the coefficient matrix.

Time-varying Lense–Thirring system [PDF]
Classical and Quantum Gravity, 2008 We consider bound geodesic orbits of test masses in the exterior gravitational field of a rotating astronomical source whose proper angular momentum varies linearly with time. The linear perturbation approach of Lense and Thirring is herein extended to the nonstationary case.

Stability of Time Varying Systems [PDF]
Volume 3A: 15th Biennial Conference on Mechanical Vibration and Noise — Vibration of Nonlinear, Random, and Time-Varying Systems, 1995 Abstract The stability behavior of time varying systems can be studied using the concept of Lyapunov exponents and their corresponding Lyapunov subspaces. For linear time varying systems the entire Lyapunov spectrum can be approximated by the Floquet exponents of periodic systems.

Finite-time stability of discrete-time systems with time-varying delay [PDF]
Chemical Industry and Chemical Engineering Quarterly, 2012 Finite-time stability can be used in all applications where large values of the state are not acceptable. In this paper, finite-time stability problem for a class of linear time-varying delay systems is studied. Based on Lyapunov-like functions method

Identification of Time-Varying Hammerstein-Wiener Systems
IEEE Access, 2020 This paper focuses on identifying time-varying Hammerstein-Wiener systems. A modified algorithm based on extended Kalman filter is proposed. The algorithm is derived from the comparison between the first and the second order extended Kalman filter ...
