This paper presents the design of a fuzzy control system applied to a multivariable nonlinear process and the state of art of fuzzy control applications in the industrial environment. The paper is divided in two parts. Initially the fuzzy control design is assessed on a horizontal balance process, a prototype in laboratory scale, with two propellers driven by two DC motors. An overview of design aspects and characteristics of industrial applications of fuzzy controllers is also included.
