Fuzzy vs PID Controller: Design Management

Abstract

Fuzzy logic was, first time presented by L.A. Zadeh in 1972 as an alternative method of classical theory control, by giving the opportunity to use a non-analytic method. During time, fuzzy logic was extensively applied in automotive, aerospace, business, electronic and even defence field, considering that is an easier way to obtain high performance. Automatic experts are constantly researching and proposing innovative and effective fuzzy control systems. The problem appears not in simulating the problem but integrating controller in an electric circuit. Therein lies the problem of the profitability of the fuzzy controller comparative to a classic PID control. Besides the time and knowledge requirements are quite different.
