A robust and fixed-time zeroing neural dynamics for computing time-variant nonlinear equation using a novel nonlinear activation function
TL;DR: A robust and fixed-time zeroing neural dynamics model is proposed and analyzed for time-variant nonlinear equation (TVNE), and comparative results demonstrate the effectiveness, robustness, and advantage of the RaFT-ZND model for solving TVNE.
