Four-Scroll Hyperchaotic Attractor in a Five-Dimensional Memristive Wien Bridge Oscillator: Analysis and Digital Electronic Implementation

Figure 11

Offset boosting dynamics in w axis (i.e.,  =  + µ): (a) phase portraits in (, x) plane and (b) the time series of (t) for discrete values of the boosted parameter µ: µ = −3 red; µ = 0 blue; µ = + 3 green. Initial conditions: x(0) = 1, y(0) = 1, z(0) = 1, (0) = 1, (0) = 0.01. The rest of the system (2a)–(2e) parameters are in Figure 2.
