“…This operation is called defuzzification. It may be accomplished by several methods, such as mean-of-maximum (MOM), centre-of-sums (COS), centre-of-mass (COM), or others [25][26][27]. The choice of defuzzification procedure is derived from a compromise between accuracy and computational effort.…”

Abstract. This paper introduces a fuzzy logic (FL) based decision support system (DSS) for a three-phase bidirectional AC-DC grid converter, working in a modern grid-like smart grid or smart industry. It is assumed that the appliances connected to that grid interact as in the Internet of Things (IoT) or like in the Internet of Everything (IoE) i.e. with a human being located in the chain of data flow. A power electronics AC-DC converter, operating as a shunt active power filter (SAPF) is selected for the case study. A harmonics reduction algorithm is presented as an implementation sample of the DSS. The operation of the SAPF is described and analysed. Experimental results showing the tuning process and operation of the laboratory model are also presented and discussed. Finally, it is shown that the DSS is an elegant and intuitive interface, which can simplify a human's or machine's decision-making process. Thanks to the DSS, the meaning of transferred data is translated into linguistic variables that can be understood by non-experts. Hence, it is expected that the amount of transferred data in the smart grid and in the IoE would be reduced. But in the same time, the high quality of the controlled process is retained, as shown by the example of a conventional SAPF.

“…FIS calculates the results based on multiple rules and each rule will give a result, therefore, fuzzy system conclusion is a fuzzy collection which should go through ambiguity resolution for getting real values. Ambiguity solution can be realized through various methods including center-of-gravity method, maximum median method and maximum mean value method [14].Center-of-gravity method for ambiguity solution is of high algorithm accuracy and can get more precise value; therefore, it gains its popularity [15]. In the paper, center-of-gravity method has been adopted.…”
