RESUMO

This work presents the project of fuzzy controllers for a X-Y coordinate table with two degrees of freedom. Both bases of the table moves horizontally, powered by tree-phases induction motors operated by frequency inverts. For detection position of bases, optical encoders were engaged to the axes of the engines to be obtained the angular displacement. A data acquisition board made the interface between a 1.4 GHz Pentium computer and the system. This board catches signals from the encoders and provides control signals to the frequency inverters. Fuzzy controllers, implemented im LabVIEM software, determinate the control variables to power the engines. Step, sine and cosine reference were used to evaluate the system performance, in position control and following trajectory. Experimental results are presented.
