A dual memristive shinriki oscillator is proposed through expanding Shinriki oscillator with an active charge-controlled memristor and substituting the series-parallel diode loop in the original circuit with a flux-controlled memristor with an absolute value term. Firstly

the mathematical model of the memristive oscillator is established according to the circuit topology diagram. Secondly

the coexisting bifurcations and routes to period-chaos transitions are analyzed when the circuit parameters are changed. Results show that Shinriki oscillator with double memristors exhibits a great dependence on parameter values and initial conditions of memristors. When the parameter values and initial conditions vary in a particular domain

the oscillator will exhibit nonlinear dynamical behaviors such as the phenomenon of coexisting antimonotonicity

incomplete symmetric behaviors

extreme multistability

etc. Moreover

the digital module circuit of the oscillator is constructed by the FPGA development board. The experimental waveform is captured on the oscilloscope

which verifies the accuracy of numerical simulation.
