摘要
This paper discusses architectural and circuit-level aspects related to hardware realizations of fuzzy controllers, A brief overview on fuzzy inference methods is given focusing on chip implementation, The singleton or zero-order Sugeno's method is chosen since it offers a good tradeoff between hardware simplicity and control efficiency, The CMOS microcontroller described herein processes information in the current-domain, but input-output signals are represented as voltage to ease communications with conventional control circuitry, Programming functionalities are added by combining analog and digital techniques, giving rise to a versatile microcontroller, capable of solving different control problems, After identifying the basic component blocks, the circuits used for their implementation are discussed and compared with other alternatives, This study is illustrated with the experimental results of prototypes integrated in different CMOS technologies.
