RECONSTRUCTING THE STATE-SPACE OF CHAOTIC BZ REACTION SYSTEM USING POWER SPECTRUM METHOD

The BZ reaction in continuous-flow stirred tank reactor (CSTR) is sele cted, and the chaotic time series in low CSTR flow rates have been ach ieved. The power spectrum method (PSM) from physics and mathematics is introduced to compute the time delay T, the embedded dimension m so a s to reconstruct the state space of the chaotic BZ reaction system by the time delayed coordinates. Further analysis and characterizations o n the reconstructed chaotic attractor show that the results are in agr eement with the references. It indicates that PSM is faster, simpler a nd reliable for processing the chaotic chemical system.
