Chaos control of a fractional order modified coupled dynamos system. (English) Zbl 1187.34080
This paper analyzes some Routh-Hurwitz stability conditions generalized to the fractional order case, and discusses the stability region of the fractional order system. The authors analyze the chaotic behavior of the fractional order modified coupled dynamos system concretely, and provide conditions suppressing chaos to unstable equilibrium points. They use the feedback control method to control chaos in the fractional order modified coupled dynamos system. Numerical simulations show the effectiveness of the method. The stability results in this paper have been generalized to 4-dimensional systems in the following reference: [A. E. Matouk, Phys. Lett., A 373, 2166–2173 (2009)].
