摘要
In this paper, we attempted to match an analytical model to the observed dynamic nonlinearity of the optical power versus driving current characteristic of lighting LED. Among the models tested were the (generalized) Wiener model, the Hammerstein model, and a variant of the generalized Wiener-Hammerstein model. Unfortunately, it turned out that neither model fits the data obtained from LED power versus current dynamic measurements.
