Online Cyber‐Physical Neural Network Model for Real‐Time Hybrid Simulation

Earthquake Engineering &Structural Dynamics, Volume 54, Issue 13, Page 3457-3474, 25 October 2025.
ABSTRACT Real‐time hybrid simulation (RTHS) is an experimental testing methodology that divides a structural system into an analytical and an experimental substructure. The analytical substructure is modeled numerically, and the experimental substructure is modeled physically in the laboratory. The two substructures are kinematically linked together at

A Hybrid Parameters Estimation Approach for Power Consumption Modeling of Ground Mobile Robots With Unknown Payload

Journal of Field Robotics, Volume 42, Issue 5, Page 1840-1860, August 2025.
ABSTRACT Typically, batteries are the main power source for mobile robots, and the practical constraints in carrying them pose challenges in achieving efficiency, autonomy, and safety objectives in robotic missions. Moreover, dealing with battery degradation requires a precise understanding of energy consumers' behavior in the system.

Anti‐Disturbance Model Predictive Control for Triaxial Servo System Based on Q‐Learning Algorithm Friction Identification

IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
This article proposes a novel model predictive control (MPC) strategy for a triaxial servo system with the capability of suppressing multiple disturbances. The discrete state‐space model is built for a triaxial servo system, considering nonlinear disturbances as constraints, and Q‐learning algorithm is used to identify the parameters of the nonlinear ...
