In this paper, a tree-based approach is proposed to design the fuzzy logic controller. Based on the proposed methodology, the fuzzy logic controller has the following merits: 1) the fuzzy control rule can be extracted automatically from the input-output data of the system and the extraction process can be done in one-pass; 2) owing to the fuzzy tree inference structure, the search spaces of the fuzzy inference process are largely reduced; 3) the operation of the inference process can be simplified as a one-dimensional matrix operation because of the fuzzy tree approach; 4) the controller has regular and modular properties, so it is easy to be implemented by hardware. Furthermore, the proposed fuzzy tree approach has been applied to design the color reproduction system for verifying the proposed methodology. The color reproduction system is mainly used to obtain a color image through the printer that is identical to the original one. In addition to the software simulation, an FPGA is used to implement the prototype hardware system for real-time application. Experimental results show that the effect of color correction is quite good and that the prototype hardware system can operate correctly under the condition of 30 MHz clock rate.
