A modified Volterra series approach for nonlinear dynamic systems modeling
IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications - Tập 49 Số 8 - Trang 1118-1128 - 2002
Tóm tắt
This paper describes a modeling approach for nonlinear dynamic systems based on a modified Volterra series; by comparing the truncation error of this series with that of the classical Volterra one, we outlined that, under the assumption of short-term nonlinear memory effects, the modified series enables a single-fold nonlinear convolution integral to be adopted also in the presence of strong nonlinearities. The measurement-based identification of the first terms of the modified Volterra series is described; experimental and simulation results which confirm the theoretical considerations are also provided.
