Conference Paper
Full-text available
Real-time hybrid simulation (RTHS) is a reliable and cost-effective experimental technique for structural performance assessment. One of the critical aspects of RTHS is the design of stable and accurate control algorithms to satisfy synchronization between numerical and experimental substructures. Dynamic compensation techniques have been proposed...

Full-text available
This study presents a robust adaptive model‐based compensation framework for real‐time hybrid simulation (RTHS), capable of minimizing synchronization errors with uncertain experimental substructures. The initial conditions of the compensator are defined using a nominal model of the transfer system without consideration of specimen–actuator interac...
Conference Paper
Full-text available
Real-time hybrid simulation (RTHS) is an experimental technique for structural testing, where a critical element is studied in the laboratory, and the rest of the structure is represented through numerical simulations. The boundary conditions on the physical specimen are imposed by a transfer system (i.e., actuators), and it is essential to minimiz...
Article
Full-text available
In this paper, a stability analysis using energy methods is performed to develop an online stability indicator for the RTHS test. This indicator's goal is to detect stability problems before it can cause excessive displacements in the system, thus avoiding damage in the physical specimen or the laboratory equipment. The effectiveness of the propose...
Conference Paper
Full-text available
La simulación híbrida en tiempo real (real-time hybrid simulation, RTHS) es una técnica experimental para realizar ensayos estructurales. Consiste en ensayar un elemento crítico en laboratorio, mientras el resto de la estructura se representa de forma numérica. En cada paso temporal se resuelve la ecuación de movimiento de la subestructura numérica...
