  • Publication number: 20240168721
    Abstract: A random transient power test signal generator based on three-dimensional memristive discrete map, which utilizes a three-dimensional parallel bi-memristor Logistic map module to generate two pseudo-random sequences, and based on the sequences, uses two waveform output modules to generate transient voltage and transient current signals respectively, thus the random transient power testing signal is obtained. The map can significantly improve the complexity of chaos and greatly extend its range of chaos. In addition, a performance evaluation shows the map has more robust hyperchaotic behavior in much larger chaos range. Moreover, the random sequences generated by the map module combines with DDS, which can generate a transient power signal with completely random period, starting phase and ending phase.
