Robust Identi cation of Takagi-Sugeno-Kang Fuzzy Models using Regularization

نویسنده

  • Tor A. Johansen
چکیده

The identiication of fuzzy models can sometimes be a diicult problem, often characterized by lack of data in some regions, collinearities and other data deecien-cies, or a sub-optimal choice of model structure. Regu-larization is suggested as a general method for improving the robustness of standard parameter identiication algorithms leading to more accurate and well-behaved fuzzy models. The properties of the method are related to the bias/variance tradeoo, and illustrated with a semi-realistic simulation example.

ORBIT - Operating-Regime-Based Modeling and Identi cation Toolkit

ORBIT is a MATLAB-based toolkit for black-box and grey-box modeling of non-linear dynamic systems. The model representation is based on multiple local models valid in di erent operating regimes, that are smoothly blended into a global non-linear model. ORBIT is a computeraided modeling environment that supports the interactive development of regime-based models on the basis of a mixture of empi...

Design of robust fuzzy Sliding-Mode control for a class of the Takagi-Sugeno uncertain fuzzy systems using scalar Sign function

This article presents a fuzzy sliding-mode control scheme for a class of Takagi-Sugeno (T-S) fuzzy which are subject to norm-bounded uncertainties in each subsystem. The proposed stabilization method can be adopted to explore T-S uncertain fuzzy systems (TSUFS) with various local control inputs. Firstly, a new design is proposed to transform TSUFS into sliding-mode dynamic systems.In addi...

A New High-order Takagi-Sugeno Fuzzy Model Based on Deformed Linear Models

Amongst possible choices for identifying complicated processes for prediction, simulation, and approximation applications, high-order Takagi-Sugeno (TS) fuzzy models are fitting tools. Although they can construct models with rather high complexity, they are not as interpretable as first-order TS fuzzy models. In this paper, we first propose to use Deformed Linear Models (DLMs) in consequence pa...

Identiication of Mimo Systems by Inputtoutput Ts Fuzzy Models

|A number of techniques have been introduced to construct fuzzy models from measured data. Most attention has been focused on multiple-input, single-output (MISO) systems. This article concentrates on the identi cation of multiple-input, multiple-output (MIMO) systems by means of product-space fuzzy clustering with adaptive distance measure (the Gustafson-Kessel algorithm). The MIMOmodel is rep...
