Along with the need to develop controllers for industrial processes, it arises the need to study advanced control techniques, such as fuzzy controllers, that can supply nonlinearities inherent in the systems. The implementation of these fuzzy controllers based on Hardware Description Language (HDL) has the advantage of high speed and fast reprogramming for use in another project, by changing only desired variables. The objective of this study is to develop a fuzzy controller implemented in VHDL (Very High Speed Integrated Circuit Hardware Description Language) for a tank level system and to evaluate its effectiveness, comparing it with a fuzzy controller developed in Matlab®. Its methodology is to develop a fuzzy system described in VHDL and divided into coding, inference and decoding for a Quanser cylindrical tank system and another system with a trapezoidal format tank. The results of this proposal were satisfactory given the limitations presented by the system
