Abstract
We present the resonant method of chaos control using light as the control parameter. The experiments have been carried out with the chemiluminescent Belousov–Zhabotinsky (BZ) reaction, which is catalyzed by a mixture of cerium and ruthenium (tris(2-2′-bipyridine)ruthenium(II) ([Ru(bpy 3)] 2+)) in a continuous-flow stirred tank reactor. The perturbation by light (470 nm) is applied in the form of rectangular light pulses at the absorption wavelength of [Ru(bpy 3)] 2+. Several unstable periodic orbits (UPO) of different periodicities (P1, P2 and P3) have been stabilized. It is demonstrated that the UPOs are embedded in the chaotic attractor. For simulations and tracking calculations, we use the 7-variable Montanator model by Györgyi and Field.
