Phase‐Advanced ADRC: Precision Missile Attitude Control via Delay Compensation
IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.This paper proposes measurement delay compensated phase‐leading linear active disturbance rejection control (MPLADRC) with a novel observer (MPLESO) integrating synchronized input filtering and phase‐lead compensation. This framework eliminates temporal signal mismatch and phase lag in missile attitude control, achieving zero steady‐state error for ...

State Estimation for Neural Networks with Leakage Delay and Time-Varying Delays
Abstract and Applied Analysis, 2013 The state estimation problem is investigated for neural networks with leakage delay and time-varying delay as well as for general activation functions. By constructing appropriate Lyapunov-Krasovskii functionals and employing matrix inequality techniques,

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.The main contribution of this paper is the consideration of information throughout the entire sampling period. By proposing a sampling point‐dependent Lyapunov functional, a new dissipative criterion and a sampled‐data control strategy are derived through the application of free‐matrix‐based integral inequalities.

Delay‐Scheduled Adaptive Observer Control Strategy for Nonlinear Systems With Time‐Varying Delays
IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.This paper proposes a delay‐scheduled adaptive observer controller for nonlinear systems with unknown time‐varying delays and bounded disturbances. By integrating an adaptive observer with an LMI‐based state‐feedback controller, the method ensures robust stability and H∞$H_\infty$ performance. Numerical simulations on delayed Lorenz and hyperchaotic Lü

Quantised MPC for LPV systems by using new Lyapunov–Krasovskii functional
IET Control Theory & Applications, 2017 This study deals with the problem of sampled‐data model predictive control (MPC) for linear parameter varying (LPV) systems with input quantisation. The LPV systems under consideration depend on a set of parameters that are bounded and available online.

Disturbance Rejection‐Based Control Design for Periodic Piecewise Polynomial Time‐Varying Systems
IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.This paper addresses a robust composite control strategy for periodic piecewise polynomial time‐varying systems with time‐delays, uncertainties, and multiple disturbances. A disturbance observer is developed to estimate matched disturbances from exogenous systems, while the observer and controller gains are obtained by solving the derived constraints ...

Regional Stabilisation of Switched Positive Systems With Unknown Equilibria
IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.A regional control framework is established for switched positive systems with multiple equilibria and unknown parameters. Both state observer and unknown parameter observer are designed. The positivity and regional stability are formulated in the form of linear programming. ABSTRACT This paper investigates the regional stabilisation of continuous‐ and

Extensions of Razumikhin's Theorem and Lyapunov-Krasovskii Functional Constructions for Time-Varying Systems with Delay * [PDF]
, 2017 International audienceWe prove extensions of Razumikhin's theorem for time-varying continuous and discrete time nonlinear systems. Our results include a novel 'strictification' technique for converting a nonstrict Lyapunov function into a strict one.

Encrypt Anything: A Content‐Aware Hierarchical Privacy Protection Method for Image Data
IET Computer Vision, Volume 20, Issue 1, January/December 2026.This paper proposes the Encrypt Anything Model (EAM), a content‐aware hierarchical privacy protection method that integrates the Segment Anything Model (SAM) and Grounding‐DINO to automatically detect and segment privacy entities in images. EAM dynamically adjusts the encryption granularity according to the sensitivity level of privacy and introduces a
