Robust Indirect Adaptive Control for a Class of Nonlinear Systems and Its Application to Shape Memory Alloy Actuators

IEEE Access, 2018
In this paper, a new robust adaptive control method has been proposed for nonlinear systems with uncertainties. This method combines the advantages of self-tuning control and sliding mode control. A simple parameterization model is first derived based on

Smart Surface Piezoelectric Sensor With High Optical Transmission

Advanced Sensor Research, Volume 5, Issue 7, July 2026.
A transparent, flexible piezoelectric pressure sensor based on structured PVDF and hybrid AgNW/SWCNT electrodes converts dynamic mechanical loading into transient electrical signals while preserving optical transmission. The multilayer architecture exhibits a high voltage response, low drift, and stable capacitive behavior, enabling the inference of ...

Isomorphic Control in Energy Storage Systems Based on Graph‐Based Digital Twins

Digital Twins and Applications, Volume 3, Issue 1, January/December 2026.
This paper proposes a graph‐based framework leveraging Activity‐on‐Edge networks to establish structural isomorphism between virtual models and physical controllers. Validated through a Mixed‐Integer Linear Programming‐based Automatic Generation Control strategy, the architecture effectively bridges the implementation gap, ensuring deterministic real ...
