Description

technical field

[0001] The present invention relates to the technical field of filtering, in particular, to a filtering method, device and electronic equipment. Background technique

[0002] In recent years, the T-S fuzzy model has received extensive attention. The T-S fuzzy model is a global model formed by smoothly connecting a series of linear sub-models with nonlinear fuzzy weights. It can approximate any smooth nonlinear model with arbitrary precision in a convex compact set. function, the T-S fuzzy model plays a huge role in the stability analysis of fuzzy systems, controller synthesis and filter design, and has achieved fruitful theoretical results.

[0003] It is worth noting that the above results are based on Type I fuzzy logic, and these traditional Type I T-S fuzzy controls usually assume that the fuzzy weights do not contain uncertainty information. However, in practical applications, it is not only nonlinear but also accompanied by uncertainty. Once the consid...
