Abstract

The invention provides a filtering method, a device and electronic equipment, and relates to the technical field of filtering. The filtering method comprises the following steps: establishing an overall interval II-type T-S fuzzy time delay system model; establishing an overall interval II-type fuzzy filter model; establishing a filtering error model according to the interval II-type T-S fuzzy time delay system model and the interval II-type fuzzy filter model, and filtering according to the filtering error model. The filtering method, device and electronic equipment provided by the invention can better process a nonlinear system with parameter uncertainty, and accomplish the design of the filter parameter, so that the filtering is more stable.

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...
