| 英文摘要 |
| This article studies the memristor characteristics and multistability of inductive wireless power transfer (WP
T) systems. Firstly, based on the sigmoid function modeling method, the equivalent memristor model of the bridge rectifier
with filter circuit is derived, and a memristor equivalent circuit model for the LCC-S type WPT proportional-integral PI
control system is established. Then, the dynamic characteristics of the system were analyzed using parameters and initial
values as bifurcation parameters. It was found that the system exhibited various dynamic phenomena such as periodic,
quasi-periodic, and point-chaotic cluster oscillations under different parameter conditions. Because the system has no equi
librium point, all the attractors it generates are hidden attractors, exhibiting special dynamic phenomena such as coexisting
multiple attractors and multistability that are extremely dependent on initial values. Finally, the memristor characteristics
and multistability of the system were verified through simulation and experiments. The results showed that the WPT PI
control system has memristive characteristics, under the same parameter conditions, different initial states produce different
f
inal states, and have completely different dynamic behaviors, which increases the uncertainty of the system. The analysis
results provide a theoretical basis for improving the stability and transmission efficiency of the control system from both
parameter and structural aspects. |
