A Markov Switching Autoregressive Model with Time-Varying Parameters

Forecasting
This study showcased the Markov switching autoregressive model with time-varying parameters (MSAR-TVP) for modeling nonlinear time series with structural changes. This model enhances the MSAR framework by allowing dynamic parameter adjustments over time.

Control system design of mechanical systems with time varying mechanical and control parameters

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2014
A new control framework of motion and/or vibration control system design for mechanical systems with a time varying mechanical and control parameters is studied. As examples of such time varying mechanical and control parameters, we can assume a variable

Finite-Time Trajectory Tracking Control for Switched Robots Based on a Time-Varying Sliding Manifold

IEEE Access
This paper investigates the trajectory tracking control problem for robots with time-varying parameters and model switching. A finite-time control scheme based on a time-varying nonsingular terminal sliding manifold is proposed.

Zeroing Neural Network With Novel Arctan Activation Function and Parameter-Varying Dual Integral Structure for Solving Time-Varying Lyapunov Equations

IEEE Access
The time-varying Lyapunov equation plays a central role in the stability analysis and control of dynamic systems across various fields. Traditional methods for dealing with time-varying Lyapunov equations often face challenges such as slow convergence ...

Keyed Hash Function Using Hyper Chaotic System With Time-Varying Parameters Perturbation

IEEE Access, 2019
Secure hash function plays an important role in cryptography. This paper constructs a hash algorithm using the hyperchaotic Lorenz system, which serves as a sponge function to absorb input message via multiple parameters time-varying perturbation. First,

Robust identification and control with time-varying parameter perturbations [PDF]

Proceedings of the 2003 American Control Conference, 2003., 2004
This paper is dedicated to the identification of parameters for a reasonably large class of nonlinear systems. We propose to design a direct parameter identification method in open loop and an indirect one in closed loop using the variable structure theory. The exponential convergence of parameter identifiers in both cases is studied.
