Introduction
This book presents new approaches to the construction of fuzzy models for modelbased control. New model structures and identification algorithms are described for the effective use of heterogenous information in the form of numerical data, qualitative knowledge and firstprinciple models. By exploiting the mathematical properties of the proposed model structures, such as invertibility and local linearity, new control algorithms have been developed which are closely related to inverse modelbased control, model predictive control, blockoriented modelbased control, and multiple model adaptive control. In this chapter the background and the concept of this framework is described.
Fuzzy Model Structures and their Analysis
This chapter gives introduces fuzzy modeling and describes the structures of fuzzy models utilized throughout this book. The successful controlrelevant application of fuzzy models requiresgenerating elements of modelbased controllers, like model inversion and linearization. The second part of this chapter presents these useful tools.
Fuzzy Models of Dynamical Systems
Modelbased engineering tools require the availability of suitable dynamical models. Consequently, the development of a suitable nonlinear model is of paramount importance. Given the highexpectations of fuzzy models in the area of identification and control, it becomes necessary to analyze and extract controlrelevant information from fuzzy models of dynamical processes. Hence, in this chapter after an introduction to the datadriven modeling of dynamical systems, the following characteristics of TS fuzzy models will be analyzed:
 Fuzzy models of dynamical systems
 Statespace realization of the model
 Prediction of the equilibrium points
 Stability of the equilibrium points
 Extraction of a linear dynamical model around an operating point
Based on this analysis, new fuzzy model structures
 Hybrid Fuzzy Convolution Model
 Fuzzy Hammerstein Model
will be proposed which can more effectively represent special nonlinear dynamic processes than conventional fuzzy systems.
 Fuzzy Model Identification
Fuzzy model identification is an effective tool for the approximation of uncertain nonlinear systems on the basis of measured data. The identification of a fuzzy model using inputoutput data can be divided into two tasks: structure identification, which determines the type and number of the rules and membership functions, and parameter identification. For both structural and parametric adjustment, prior knowledge plays an important role. Hence, in this book the rules of the fuzzy system are designed based on the available a priori knowledge and the parameters of the membership, and the consequent functions are adapted in a learning process based on the available inputoutput data. Hence, this chapter is devoted mainly to the parameteridentification of the proposed fuzzy models, but certain structure identification tools are also discussed.
Fuzzy Model Based Control
This chapter discusses how the proposed fuzzy models can be used in modelbased control. The developed Takagi  Sugeno, Hybrid Fuzzy Convolution and Fuzzy Hammerstein dynamic fuzzy models will be applied in several inversion and linearizationbased control schemes. Taking the identification of the Takagi  Sugeno fuzzy models into account, guidelines will be given as which control configuration is most advantageous.
Process Models Used for Case Studies
In this section the models used in the application examples are presented.
