Self-Excited and Hidden Chaotic Attractors in Matouk’s Hyperchaotic Systems

Self-excited and hidden chaotic attractors are interesting complex dynamical phenomena. Here, Matouk’s hyperchaotic systems shown to have self-excited attractors, respectively. Two case studies of provided which examined with orders 3.08 3.992, Moreover, found in the fractional-order system its integer-order counterpart. The existence one-eyed face is also reported this work. Our results show that fractional derivative affects appearances system.
