A New Piecewise Linear Hyperchaotic Circuit
Chunbiao Li, Julien Clinton Sprott, Wesley Thio, and Huanqiang Zhu
When the polarity information in diffusionless
Lorenz equations is preserved or removed, a new piecewise linear
hyperchaotic system results with only signum and absolute-value
nonlinearities. Dynamical equations have seven terms without any
quadratic or higher order polynomials and, to our knowledge, are
the simplest hyperchaotic system. Therefore, a relatively simple
hyperchaotic circuit using diodes is constructed. The circuit
requires no multipliers or inductors, as are present in other
hyperchaotic circuits, and it has not been previously reported.
