Solution to Asymptotic Stability in Tracking Control of Nonlinear Systems With Control Input Differentiation, Actuator Dynamics, and Saturation Constraints

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
The work delivers a rigorous mathematical framework for asymptotic tracking in nonlinear systems that explicitly include control‐input derivatives, actuator dynamics, and input saturation, with Lyapunov‐based proofs establishing convergence and robustness under their coupled effects.

Slow Relaxation and Phase Space Properties of a Conservative System with Many Degrees of Freedom

, 1994
We study the one-dimensional discrete $\Phi^4$ model. We compare two equilibrium properties by use of molecular dynamics simulations: the Lyapunov spectrum and the time dependence of local correlation functions.

Enhanced Control Strategies for Lower Limb Rehabilitation Robots: A Comparative Study of MRAC, PID‐ZN, and MRAC‐PSO Controllers

Applied Bionics and Biomechanics, Volume 2026, Issue 1, 2026.
Wearable robots for rehabilitation have dramatically advanced the medical field regarding helping patients suffering from lower limb impairments to regain mobility and ameliorate their range of motion (ROM). However, to further optimize control mechanisms within these robots, conventional methods cannot adapt to the different needs of patients in their

The Dynamical Landscape of the Negative‐Order (3+1)‐Dimensional Calogero–Bogoyavlenskii–Schiff Equation

Journal of Mathematics, Volume 2026, Issue 1, 2026.
A new negative‐order form of the (3 + 1)‐dimensional Calogero–Bogoyavlenskii–Schiff equation is examined in this investigation. This equation plays an important role in accurately describing the thermodynamic properties of mixtures, particularly in chemical engineering applications.

Model Predictive Contouring Control With Barrier and Lyapunov Functions for Stable Path-Following in UAV Systems

IEEE Access
In this study, we propose a novel method that integrates Nonlinear Model Predictive Contour Control (NMPCC) with an Exponentially Stabilizing Control Lyapunov Function (ES-CLF) and Exponential Higher-Order Control Barrier Functions to achieve stable path-

Nonlinear Position Control Using Only Position Feedback under Position Errors and Yaw Constraints for Air Bearing Planar Motors

Mathematics, 2020
In this paper, we propose a nonlinear position control using only position feedback to guarantee the tolerances for position tracking errors and yaw. In the proposed method, both mechanical and electrical dynamics are considered.

Lyapunov‐Based Control of Circular Robot Formations With Limited Field of View

Artificial Intelligence for Engineering, Volume 1, Issue 2, Page 83-94, 29 December 2025.
A nonlinear vision‐based control framework ensures safe leader–follower formation of wheeled mobile robots under limited camera field‐of‐view. The Lyapunov‐based controller guarantees persistent visibility, prescribed‐time convergence, and uniform circular formation, validated through real‐time experiments on Quanser QBot platforms.

Finite-Time Adaptive Quantized Control for Quadrotor Aerial Vehicle with Full States Constraints and Validation on QDrone Experimental Platform

Drones
The issue of finite-time stability has garnered significant attention in the control systems of quadrotor aerial vehicles. However, existing techniques for achieving finite-time control often fail to consider the system’s state constraint characteristics

Constrained Geometric Attitude Control on SO(3)

, 2017
This paper presents a new geometric adaptive control system with state inequality constraints for the attitude dynamics of a rigid body. The control system is designed such that the desired attitude is asymptotically stabilized, while the controlled ...

Monocular visual servo control of a quadcopter for crossing windows, doors, and corridors

Asian Journal of Control, Volume 27, Issue 6, Page 2706-2723, November 2025.
Abstract This paper proposes a sequential visual servo control scheme for quadcopters, where the main goal is to drive a quadcopter to a desired pose while crossing windows, doors, or corridors using only visual feedback. This control scheme is composed of two stages that act in sequence: the approaching and pose regulation phases.
