Design of a fuzzy set controller using FPGA for cim application.

摘要

In this paper is presented a FPGA design of a Fuzzy Set Controller acting under a restricted structure of PI+PD operation, called "linear". The goal of the design is to take advantage of the charactheristics of computing facilities, flexible configuration, sinference simplicity, and wide range of application, with others restrictions imosed to the model used, it can reforece linear and non linear operations, and also to have all the attributes in one chip witha specialized and dedicated structure, with very fast dynamics process due to FPGA design. This characteristics is innovative, because of most of the Fuzzy Set Controller implemented by hardware are not SISO, using aproximation in the computation to have fast response. In our case, it is obtained good exactitude, spped and several options of configuration.
