The Control Theory And Circuit Experiment Study Of Chaos By Means Of Delayed Feedback

Control of Chaos, hyperchaos, and Chaos of spatio-temporal are researched by means ofdelayed feedback in this paper, and they are realized in circuit experiments and simulation aswell as theoretic analysis and numerical calculation. At last, it ends with respective reasonableconclusion to problems of Chaos', hyper chaos', and Chaos' system of spatio-temporal.In this paper, based on the theory of "Hopf Bifurcation", control of the continual timechaos by the method of enhancing delayed feedback is realized in circuit simulation.In addition circuit experiments and numerical calculation succeeds in feasibility ofdiscrete hyperchaos system's delayed feedback and enhancing delayed-feedback control.Another design scheme of circuits making three-coupled map lattice model is proposedin this paper. The circuit experiment, circuit simulation, theoretical analysis and numericalcalculation reaches the same conclusion respectively that delayed feedback may perfectly andeffectively control one-way three-coupled ring map lattice.This paper studies Chaos, hyperchaos, and Chaos of spatio-temporal by circuitexperiments and circuit simulation, and undoubtedly the conclusions are very important andhelpful for further researches in such subjects.
