Nonlinear Systems, Fuzzy Modeling And Control

The intelligent control is a new field in the technology discipline and it is also in anadvanced development process of control theory. The purpose for using intelligentcontrol is solving complex control problems which could not be solved by conventionaland traditional methods. As a main branch of intelligent control, Fuzzy control has beendeveloped for over 20 years which makes fuzzy control attain many greatnessachievements no matter in the field of theory or applications, therefore fuzzy control isgoing to be considered as one of the most important technology in the field of researchand application for the future years.Fuzzy control theory is mainly used to solve those dramatic non-linear complexsystems. It is a control method which is based on fuzzy set-theory, fuzzy languagevariables and fuzzy logic consequence. By the definition of linear control and non-linearcontrol point view, fuzzy control is a non-linear control.Firstly, this paper describes the creation background, the research status anddevelopment direction of fuzzy control theory.It also introduces the basement theory offuzzy control.Secondly, this paper analyzes T-S model and Fuzzy Hyperbolic Model. Based onthe original modeling method of T-S model, this article makes some improvements,creates a multinomial fuzzy model, also particularly describes its modeling method, andthrough the emulator result of real examples proving the validity of this method.Thirdly, this paper creates two new fuzzy controllers and names them as new typefuzzy controller and newⅠtype fuzzy controller. It describes the designing method andtheory of these two new controllers. Based on new type fuzzy controller it creates thenewⅠtype fuzzy controller. Analyze results from these two new fuzzy controllers viathe examples, and compare the results from traditional Two-Dimension fuzzy controller,and then prove the newⅠtype fuzzy controller can get an effective control. Finally, it summarizes the whole article, includes the main point, also points out thefuture research direction.
