Atenuación de efectos pendulares en grúas-torre usando control por rechazo activo de perturbaciones en tiempo discreto con observador resonante Horacio Coral-Enriquez Santiago Pulido-Guerrero Ingeniería torre resonador tiempo discreto control de grúas observador de perturbaciones En este artículo, se propone un esquema de control en tiempo discreto basado en el enfoque del rechazo activo de perturbaciones (ADR) para abordar el problema de control de oscilaciones en la carga de grúas-torre sujetas a incertidumbres paramétricas y perturbaciones externas. El esquema de control propuesto usa un observador extendido que incorpora un modelo interno resonante diseñado para mejorar la estimación de variables de estado y perturbaciones, en especial las provenientes de la oscilación de la carga. La ley de control se diseña para rechazar las perturbaciones en línea y acomodar la dinámica de lazo cerrado. La propuesta de control se valida experimentalmente en una grúa-torre a escala, y es comparado con un PI-vectorial y otro control basado en el enfoque ADR. Los resultados experimentales muestran que el esquema propuesto presenta mejor desempeño para reducir las oscilaciones en la carga y exhibe mejoras sustanciales en el rechazo de perturbaciones. 2018 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49655628008 https://www.redalyc.org/journal/496/49655628008/ https://www.redalyc.org/journal/496/49655628008/html/ https://www.redalyc.org/journal/496/49655628008/49655628008.epub https://www.redalyc.org/journal/496/49655628008/movil 10.15446/dyna.v85n204.63245 es http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.204 Vol.85
