Sugeno/ Mamdani Interval Type II Fuzzy Logic Controller Based DSTATCOM with Controlled Load

The controlling method of DSTATCOM device attracts many researchers because it affects the performance of the mentioned device. Recently, interval type II fuzzy logic controller has been used in many aspects of electrical engineering for controlling power electronics devices. MATLAB R2022b provides the researchers with two different types of interval type II fuzzy logic, Mamdani and Sugeno types and the ability to convert among them easily. In this paper, Mamdani and Sugeno interval type II fuzzy logic controllers with two different control algorithms were examined by means of MATLAB R2022b Simulink environment along with the tuning process. The Mamdani interval type II fuzzy logic controller with centroid defuzzification method gives the best performance of DSTATCOM device at controlled rectifier loads with both examined controlled algorithms UVT and SRF.
