Analytical Structures and Analysis of Simplest Fuzzy PD Controller with Asymmetrical/Symmetrical, Trapezoidal/Triangular/Singleton Output Membership Function
نویسنده
چکیده
In this paper, analytical structure of Simplest fuzzy controllers are derived for Center of Sum and Height defuzzification methods, under Mamdani Minimum and Larsen Product reasoning, using asymmetrical/ symmetrical, trapezoidal/ triangular/singleton output membership function. The drawbacks, errors of existing analytical structures are discussed and revised accordingly. The analysis of derived structures has been done using variation of nonlinearity. Role of various parameters over performance of control system have been studied. The proposed analytical structures are applied to control systems to validate the theoretical studies. Performance enhancement of simplestFLC using asymmetrical trapezoidal membership function is explained with control application. Copyright c © 2007 Yang’s Scientific Research Institute, LLC.
