Interactive T-S fuzzy semantic model estimation method and system and computer readable storage medium

Abstract

The invention discloses an interactive T-S fuzzy semantic model estimation method and system and computer readable storage medium, which are used for target tracking and solve the problem that the robustness and the accuracy of a research result are reduced because an existing filtering algorithm is difficult to meet the requirement of system performance, including defining different semantic fuzzy sets in a T-S fuzzy model by adopting different language values; setting a probability conversion method among the semantic fuzzy sets; carrying out fuzzy interaction on the initial state of the target to obtain mixed initial state estimation and mixed initial state covariance; carrying out hybrid initial state estimation and hybrid initial state covariance nonlinear filtering processing to obtain an updated state and an updated state covariance; performing calculation and updating on the precursor parameters of the T-S fuzzy model to obtain updated precursor parameters; calculating a standardized model probability; obtaining state estimation and covariance estimation of the target; and the motion state of the target is estimated, so that the robustness and accuracy of the research result are improved.

Description

technical field [0001] The present invention relates to the technical field of target tracking, in particular to an interactive T-S fuzzy semantic model estimation method, system and computer-readable storage medium. Background technique [0002] Takagi and Sugeno proposed the T-S fuzzy model in 1985, and the then part of the model is expressed in the form of a linear function. [0003] The state estimation of nonlinear and non-Gaussian stochastic systems has a wide range of applications in modern signal processing, image processing, computer vision and automatic control; extended Kalman filter, unscented Kalman filter, volumetric Kalman filter and many Kalman class Improve filtering and other methods. [0004] However, this kind of filtering method can only complete the system filtering of weak nonlinear and noise approximate Gaussian model. When the system is strongly nonlinear and non-Gaussian noise, the filtering algorithm is difficult to meet the requirements of system...
