Determining accurate Lyapunov exponents of a multiscroll chaotic attractor based on SNFS

VH Carbajal-Gómez, C Sánchez-López - Nonlinear Dynamics, 2019 - Springer
In n-scroll attractors design using active devices, the behavior of the nonlinear part is, often,
modeled by using a piecewise linear (PWL) approach. Although little effort is required to …
