Resumo

One of the greatest advances of the development of control systems was the emergence of fuzzy logic, because it deals with imprecise information, which often is not seen by conventional controllers. Without the mathematical model of the system to be controlled, the fuzzy controller is a real and effective alternative for the control of non-linear process. The technology industry has grown in the creation of small-sized devices, and nowadays there are fuzzy controllers running inside of portable devices with microcontrollers. This technique is not well known and brings great advantages. This article describes a simple discretization of a fuzzy control system for a later deployment to a micro controlled circuit.
