Estimation of parametric convergence bounds for Volterra series expansion of nonlinear systems
A parametric convergence bound of Volterra series expansion of NARX models is derived. A novel concept is introduced to indicate the margin before Volterra series expansion diverges. A fundamental basis for nonlinear analysis and design using Volterra series based methods. A significant insight into understanding nonlinear influence (super/sub harmonics, etc.).
