Preassigned-Time Projective Lag Synchronization of Octonion-Valued BAM Neural Networks via Exponential Quantized Event-Triggered Control

Mathematics
This study addresses the preassigned-time (PDT) projective lag synchronization of octonion-valued BAM neural networks (OV-BAMNNs) through exponential quantized event-triggered control (ETC). First, an OV-BAMNN model incorporating discontinuous activation

Predefined‐Time Fault‐Tolerant Control of Rigid Spacecraft With Prescribed Performance

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.
This paper proposes a predefined‐time fault‐tolerant control strategy to address the attitude tracking problem of rigid spacecraft. To ensure both transient and steady‐state performance of attitude tracking, prescribed performance functions are introduced, and coordinate transformations are employed to convert constrained tracking errors into ...

Offline Pulse Distribution Strategies for SWISS Rectifier Using Improved PDM at High Switching Frequencies

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper proposes an improved offline pulse density modulation strategy for the SWISS rectifier to achieve low input current distortion and high power factor at high switching frequencies. Experimental results at 38.4 kHz reduce THDi from over 30% to ≈10%, while high‐frequency simulations at 172.8 kHz achieve THDi of 3.3% and PF = 0.9954.

MXene‐Integrated Printed Piezoresistive Flexible Sensors: A Breakthrough in Real‐Time Monitoring for Medical and Smart Applications

Advanced Science, Volume 12, Issue 40, October 27, 2025.
A chocolate‐inlaid Ag@waffle‐structured MXene is synthesized in this research via template‐directed growth strategy (WSM‐A8). The pressure sensor prepared with the WSM‐A8 presents the highest ΔI/I0 response intensity among the reported MXene‐based piezoresistive sensors with satisfactory sensitivity, outstanding structural stability, and superior ...

Analytical Solutions of the Driven Time‐Dependent Jaynes–Cummings Model

Annalen der Physik, Volume 537, Issue 10, October 2025.
Following the great strides made in the last decade towards the control and tunability of physical parameters in cavity quantum electrodynamics, this study presents new solutions to the dynamics of the time‐dependent Jaynes–Cummings model with variable external classical fields acting on the two‐level system and the quantized field mode.

Reprogrammable Soft Pneumatic Metamaterials with Multimodal Twisting and Tunable Multistability

Small Structures, Volume 6, Issue 9, September 2025.
This work introduces a novel material concept that allows reprogrammability of both multimodality and multistability in soft pneumatic metamaterials, thereby sealing multifunctionality in a single prototype. The strategy is applied to design a soft robotic arm that can attain multiple deformed trajectories while operating using ON/OFF pneumatic ...

Disturbance Observer Based Adaptive Control Scheme for Synchronization of Fractional Order Chaotic Systems With Input Delay

IET Control Theory &Applications, Volume 19, Issue 1, January/December 2025.
In this paper, an adaptive arbitrary time controller is proposed for the synchronization of fractional order chaotic systems. An adaptive disturbance observer is presented, capable of exponentially estimating unknown disturbances in arbitrary time.

Finite‐Time Consensus Pinning Control Method for Multiple Inverters–Paralleled Photovoltaic Microgrid

International Transactions on Electrical Energy Systems, Volume 2025, Issue 1, 2025.
Multiple inverters–paralleled photovoltaic microgrid is a typical cyber‐physical system with varying line impedances and unsynchronized nodes that result in unbalanced power sharing and are prone to cause circulating current. Therefore, a complex network based on a finite‐time consensus pinning control method for microgrids is proposed in this paper ...

Cloud‐mediated self‐triggered synchronisation of a general linear multi‐agent system over a directed graph

IET Cyber-Physical Systems: Theory &Applications, Volume 9, Issue 4, Page 497-508, December 2024.
The authors propose a self‐triggered synchronisation control method of a general linear time‐invariant multi‐agent system through a cloud repository. Under asynchronous communication through a cloud, each agent has to handle uncertainties on the behaviours of its neighbouring agents as well as itself.
