The theory of fuzzy sets is a methodology for the handling of qualitive, inexact, imprecise information in a systematic and rigorous way. Conventional control approaches require a mathematical model of the process or system to be controlled. However, when an accurate knowledge of the process dynamics is not available, or the process is highly complex or non linear, conventional techniques do not give satisfactory results and human control operators must still be used. In contrast, fuzzy logic captures and utilizes the accumulated empirical know-how of human operators expressed in qualitative, inexact, imprecise ways
