| Control of Chaos, hyperchaos, and Chaos of spatio-temporal are researched by means ofdelayed feedback, pulse disturbance, prediction feedback and prediction delayed feedback inthis paper, and they are realized in circuit experiments and simulation as well as theoreticanalysis and numerical calculation. At last, it ends with respective reasonable conclusion toproblems 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 delayed feedback is realized in circuit simulation. In addition circuitexperiments and numerical calculation succeeds in feasibility of discrete hyperchaos system'sdelayed-feedback control. The control of discrete chaos in the circuit by the method of pulse disturbance to systemvariables is realized. A various of stable periodic orbits are obtained by properly adjustingpulse intervals and feedback coefficient. An improved prediction feedback control method is proposed and used in chaos systems,and circuit experiments, theoretic analysis and numerical calculation proves its feasibility. Another design scheme of circuits making coupled map lattice model is proposed in thispaper. The circuit simulation, theoretical analysis and numerical calculation reaches the sameconclusion respectively that prediction feedback and delayed feedback may perfectly andeffectively control one-way and two-way 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.
