چکیده
Fuzzy set theory has shown potential for reducing uncertainty as a result of data sparsity and also provides advantages quantifying gradational changes like those pollutant concentrations through fuzzy clustering based approaches. The ability to lower the sampling frequency perform laboratory analyses on fewer samples, yet still produce an adequate distribution map, would reduce initial cost new remediation projects. To assess modeling make spatial predictions using sample points, its predictive was compared with ordinary kriging (OK) inverse distance weighting (IDW) methods under increasingly sparse conditions. This research used Takagi–Sugeno (TS) modelling approach c-means (FCM) lead in soil. performance TS model very dependent number outliers respective validation set. For conditions, FCM constant width Gaussian shaped membership functions did not show any over IDW OK type tested. Therefore, it possible speculate reduction delineating extent contamination

Takagi–Sugeno Fuzzy Modeling of Skin Permeability
The skin is a major exposure route for many potentially toxic chemicals. It is, therefore, important to be able to predict the permeability of compounds through skin under a variety of conditions. Available skin permeability databases are often limited in scope and not conducive to developing effective models. This sparseness and ambiguity of available data prompted the use of fuzzy set theory ...
متن کاملFtsm — Fast Takagi-sugeno Fuzzy Modeling
Takagi-Sugeno type fuzzy models are widely used for model-based control and model-based fault diagnosis. They provide high accuracy with relatively small and easy to interpret models. The problem that we address in this paper is that data driven identification of such fuzzy models is computationally costly. Whereas most identification algorithms for Takagi-Sugeno models restrict the model’s gen...
متن کاملTakagi-Sugeno Fuzzy Sampled-data Filter for Nonlinear System
This paper presents the stability conditions of the Takagi-Sugeno (T-S) fuzzy sampled-data filter. The error system between the T-S fuzzy system and fuzzy filter is presented. In the sense of the Lyapunov stability analysis, the stability conditions are given, which can be represented in terms of linear matrix inequalities (LMIs). The proposed stability conditions utilize the different approach...
متن کاملObservers for Takagi-Sugeno fuzzy systems
We focus on the analysis and design of two different sliding mode observers for dynamic Takagi-Sugeno (TS) fuzzy systems. A nonlinear system of this class is composed of multiple affine local linear models that are smoothly interpolated by weighting functions resulting from a fuzzy partitioning of the state space of a given nonlinear system subject to observation. The Takagi-Sugeno fuzzy system...
