New adaptive filter enhances state estimation for nonlinear systems

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new adaptive split-combine Gaussian mixture filter (AMF) designed to accurately estimate the probability density function (PDF) of states in nonlinear and multimodal systems. This filter addresses limitations in existing Gaussian mixture filters by adaptively splitting and combining Gaussian particles without requiring online numerical optimization. The AMF demonstrates superior performance compared to baseline filters on benchmarks involving Van der Pol oscillators and the Lorenz attractor, with a parallel implementation enhancing its computational efficiency for high-fidelity PDF estimation.

    An adaptive split-combine Gaussian mixture filter for nonlinear and multimodal state estimation

    arXiv:2608.04430v1 Announce Type: cross Abstract: Filtering combines model predictions with measurements to estimate the probability density function (PDF) of a system state over time. The PDF often becomes highly asymmetric and even multimodal in nonlinear systems with oscillato…
