“…Estas técnicas de compensación de retardos se han aplicado al control de procesos de deshidratación de alimentos (Santos-Sánchez et al, 2016, 2021, al control de altura de quadrotores en base a medidas de visión y GPS (Ordaz et al, 2013), a la atenuación de vibraciones de edificios (Vite et al, 2020), a la predicción del número real de infectados en epidemias (Castaños and Mondié, 2021), al control de formaciones de robots no holonómicos (Velasco-Villa et al, 2021) y de flotas de vehículos (Vite et al, 2021b), a problemas de consenso (Fragoso-Rubio et al, 2019) y al control de procesos quimícos (Hernández-Pérez et al, 2020).…”

Se introducen resultados recientes del enfoque de funcionales de Lyapunov-Krasovski de tipo completo para sistemas lineales con retardos. Se explican brevemente los principales conceptos y resultados para el caso de sistemas con un retardo así como las condiciones necesarias y suficientes de estabilidad expresadas en terminos del análogo de la matriz de Lyapunov. Las extensiones de este tipo de condiciones de estabilidad a otras clases de sistemas con retardos son expuestas brevemente. Tambien se presentan aplicaciones existentes del efoque de funcionales de tipo completo a problemas de analisis y de diseño de controladores. El trabajo se enfoca a contribuciones de investigadores de Mexico a este tema de estudio.

“…In Enríquez-Zárate et al (2020) a model-based predictive controller parameterized with Laguerre functions was designed for a building-like structure with a passive vibration absorber. Subsequently, the vibration control of seismically excited building structures in the presence of the delayed input by means of a scriptH∞ prediction approach is addressed in Vite Hernández et al (2020). The authors in Lezgy-Nazargah et al (2020) proposed state feedback and dynamic output feedback controllers by using the scriptH∞ control theory for vibration suppression in buildings considering time-delay effects in the measurements.…”

This paper develops a robust observer for a class of linear systems subject to unknown signals, uncertainties, and disturbance output measurements for building structure systems. The highlight of the proposed observer is that it mitigates the adverse effects present in physical systems as it happens with the structural systems of buildings. The proposed robust observer provides a simultaneous estimation of building displacements and velocities (state vector) and the seismic force acceleration signal (unknown input) from noisy acceleration measurements of the structure. These estimations can help to reduce the displacements of building structure systems with the aid of a vibration controller. The convergence analysis of the proposed robust observer is based on Lyapunov theory, which resulted in a simple set of Linear Matrix Inequalities. An example considering a two-story building-like structure was performed to illustrate the effectiveness of the proposed observer.
