Observer Design for Vector Nonlinear Systems With Applications to Autonomous Vehicles and Robots

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper focuses on observer design for nonlinear systems involving functions of vector arguments. The output equations and the process dynamics are both composed of nonlinear functions of nonseparable multivariable states. The partial derivatives of the nonlinear functions are assumed to be bounded.

Privacy‐Preserving Data‐Driven Distributed MPC for Heterogeneous Nonlinear Multi‐Agent Systems

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Distributed model predictive control (DMPC) is a cornerstone for coordinating multi‐agent systems, yet simultaneously ensuring data privacy, handling unknown nonlinear dynamics, and managing heterogeneous constraints remains an open challenge.

Improved Robust Stability Criteria of Uncertain Neutral Systems with Mixed Delays

Abstract and Applied Analysis, 2009
The problem of robust stability for a class of neutral control systems with mixed delays is investigated. Based on Lyapunov stable theory, by constructing a new Lyapunov-Krasovskii function, some new stable criteria are obtained.

Projection methods for large Lyapunov matrix equations

, 2006
In the present paper, we propose Krylov subspace methods for solving large Lyapunov matrix equations of the form AX+XAT+BBT=0 where A and B are real n×n and n×s matrices, respectively, with s≪n.

Neural Network‐Based Runtime Monitoring and Control for Unknown Nonlinear Systems

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Real‐time system monitoring and stabilization become especially challenging when the system dynamics are unknown. This article introduces a novel design for monitoring and stabilizing unknown nonlinear systems with measurement noise. The design utilizes a generic modelling framework by decomposing the system into a known tunable linear ...

Friction‐Aware Force‐Realizable Safety Control for Four‐Wheel Independently Steered and Driven Mobile Robots

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Safety‐critical control remains a major challenge for four‐wheel independently steered and driven (4ISD) mobile robots, where high‐accuracy path tracking and obstacle avoidance must be achieved under over‐actuated steering–driving coordination, tire–ground friction limits, and wheel‐torque constraints.

Error analysis of QR algorithms for computing Lyapunov exponents [PDF]

, 2001
Lyapunov exponents give valuable information about long term dynamics. The discrete and continuous QR algorithms are widely used numerical techniques for computing approximate Lyapunov exponents, although they are not yet supported by a general error ...

Lyapunov — Krasovskii functional with prescribed derivative and Lyapunov matrix for the wave equation

Vestnik of Saint Petersburg University. Applied Mathematics. Computer Science. Control Processes
This paper considers a boundary value problem for a one-dimensional wave equation with Dirichlet boundary conditions. A quadratic Lyapunov — Krasovskii functional is constructed, whose derivative along the solutions coincides with a prescribed negative definite quadratic form. Such functionals are a standard tool in the analysis of stability and robust
