| Abstract: | Various uncertain factors unavoidably exist in engineering applications, and adopting uncertain models can more accurately reflect dynamic systems’ characteristics.Dynamic modeling of parametric uncertainty has received full attention in last 30 years, while uncertain non-parametric dynamic modeling as a newer study field receives attention in recent years.This field has obtained a lot of study achievements up to now.It is necessary to comprehensively review the status of research and development at home and abroad in this field.Here, the research status and advances for approaches, theoretical basis, modeling process and application of uncertain non-parametric dynamic modeling were reviewed systematically.The existing problems now were summarized and development directions of future study in this field were pointed out. |
