Título: | Towards the IC implementation of adaptive fuzzy systems |
Autor: | Baturone, Iluminada CSIC ORCID; Sánchez-Solano, Santiago CSIC ORCID ; Huertas-Díaz, J. L. CSIC | Fecha de publicación: | 1998 | Editor: | Institute of Electronics, Information and Communication Engineers | Citación: | IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences E81-A(9): 1877-1885 (1998) | Resumen: | The required building blocks of CMOS fuzzy chips capable of performing as adaptive fuzzy systems are described in this paper. The building blocks are designed with mixed-signal current-mode cells that contain low-resolution A/D and D/A converters based on current mirrors. These cells provide the chip with an analog-digital programming interface. They also perform as computing elements of the fuzzy inference engine that calculate the output signal in either analog or digital formats, thus easing communication of the chip with digital processing environments and analog actuators. Experimental results of a 9-rule prototype integrated in a 2.4-μm CMOS process are included. It has a digital interface to program the antecedents and consequents and a mixed-signal output interface. The proposed design approach enables the CMOS realization of low-cost and high-inference fuzzy systems able to cope with complex processes through adaptation. This is illustrated with simulated results of an application to the on-line identification of a nonlinear dynamical plant. | Versión del editor: | http://search.ieice.org/bin/summary.php?id=e81-a_9_1877 | URI: | http://hdl.handle.net/10261/84976 | Identificadores: | issn: 0916-8508 e-issn: 1745-1337 |
