[0002] At present, the method of constructing four-dimensional hyperchaotic is mainly to add one dimension to form a four-dimensional hyperchaotic system on the basis of the three-dimensional chaotic system. Memristor, as a new physical component discovered by Hewlett-Packard Laboratory in 2008, can replace Chua's diode in Chua's circuit To form a four-dimensional chaotic system, two memristive elements are needed to form hyperchaos in Chua's circuit, so a five-dimensional or more system is required, and there are relatively few system circuits that realize hyperchaos in a four-dimensional system with memristive elements , a memristive hyperchaotic system with four-wing attractors has not been proposed yet, which is the shortcoming of the existing technology
