A simplified symmetry chaotic circuit was designed and implemented to reduce circuit cost and improve stability and flexibility. The change of symmetry chaotic dynamic behaviors can be achieved by adjusting the time constant. The circuit experiments were in good agreement with numerical simulation and theoretical analysis.
In order to reduce the circuit cost and improve the stability and flexibility of the circuit, a simplified symmetry chaotic circuit was designed and implemented by using an inverse integration circuit and a voltage follower as isolators. The change of different symmetry chaotic dynamic behaviors caused by the change of parameters can be realized by adjusting the time constant. The behavior coexistence characteristics and amplitude control characteristics under different initial conditions were verified. The results of circuit experiments are in good agreement with those of numerical simulation and theoretical analysis. This method is effective and feasible.
