Constructing a Memristive Chaotic Oscillator With Two-Dimensional Offset Boosting

By designing a proper electromagnetic constraint within a memristor, and introducing it into a dynamical system with the increase of dimension, a class of memristive chaotic systems with two-dimensional offset boosters is constructed. One offset constant directly applies offset boosting of a system variable while the other modifies the offset of two variables simultaneously. Furthermore, when the derived structure satisfies a specific feedback balance law, the property of total amplitude control can be obtained. The circuit implementation is consequently realized and the results are in line with the theoretical analysis.
