Nonsingular Terminal Sliding Mode Control of the Yarn Winding Process Based on a Finite-Time Extended State Observer by Jieshi Yang, Yinghao Ye, Yun Cheng, Liang Hua

“…The finite-time stability of the estimation error and system tracking error is analyzed using the Lyapunov method. Finally, the simulation results demonstrate that the proposed control scheme effectively achieves finite-time stability of both estimation and tracking errors, and exhibits favorable dynamic characteristics.…”

Chaos in the butterfly cone by Márk Mezei, Gábor Sárosi

“…It has been previously observed that the growth of these effects is organized along rays and can be characterized by a velocity dependent Lyapunov exponent, λ(v). We show that this exponent is bounded inside the butterfly cone as λ(v) ≤ 2πT (1 − |v|/vB), where T is the temperature and vB is the butterfly speed. …”
