Wang, Pei; Li, Damei; Hu, Qianli Bounds of the hyper-chaotic Lorenz-Stenflo system. (English) Zbl 1222.37036 Commun. Nonlinear Sci. Numer. Simul. 15, No. 9, 2514-2520 (2010). Summary: To estimate the ultimate bound and positively invariant set for a dynamical system is an important but quite challenging task in general. This paper attempts to investigate the ultimate bounds and positively invariant sets of the hyper-chaotic Lorenz-Stenflo (L-S) system, which is based on the optimization method and the comparison principle. A family of ellipsoidal bounds for all the positive parameters values \(a\), \(b\), \(c\), \(d\) and a cylindrical bound for \(a>0\), \(b>1\), \(c >0\), \(d>0\) are derived. Numerical results show the effectiveness and advantage of our methods.
