MUNOZ AGUIRRE, E.  y  ALEXANDROVA, O.. Estabilidad robusta de la posición vertical de dos péndulos acoplados por un resorte. Rev. mex. fis. [online]. 2004, vol.50, n.2, pp.127-133. ISSN 0035-001X.

In the present work we find the equations governing the movement of two coupled pendulums with a spring of elasticity constant K and we make a study of the robust stability when the system is subjected to a vertical acceleration. Likewise we make an brief analysis of the influence of the spring constant on the stability of the spring.

Palabras llave : Robust stability; Pontriaguin maximal principle; small oscilations.
