A mathematical model of a flux-controlled meminductoris proposed, which is directly from the definition. A practical floating flux-controlled meminductor emulator is implemented with common off-the-shelf components based on the model, which does not contain any memristor.In the different signals and parameters, the system-level circuit simulation experiments are presented by Matlab and Multisim simulation platform.The implementation of hardware circuit and the results of performance tests are presented. Software simulation and hardware test results show that the flux-current relation of the equivalent meminductor typically behaves as a pinched hysteresis loop characteristic and depends on the frequencies and amplitudes of applied voltage stimulus, which indicates that it is a kind of nonlinear inductor with memory and accords with the concept of meminductor.It provides for the devices simulation entities to carry out new application circuits in electronic field.
