Abstract
Fuzzy logic is a control system, which is able tosimulate the decision making capability of an experienced human being. Using human knowledge it is able to solve complex real world problems, which might require excellent human intelligence. In the industrial world Fuzzy logic applications have been in use since long time. Fuzzy logic’s expert high grade decision making ability has allowed it to be used in areas such as flow process plants, power plants, thermal process plants, oil refineries, diagnosing medical problems, etc. Chemical processes are well-known for difficulties such as large variations in output responses and non-linearity. Thus it is difficult to control these processes using the conventional regulating mechanisms. This paper provides an overview on some researches, some pioneering and some path-breaking, which have been conducted in last few decades, in the area of Fuzzy logic controller design and highlights the important characteristics in design of Fuzzy logic controller for chemical industrial applications.
