Development of IP Modules of Fuzzy Controllers for the Design of Embedded Systems on FPGAs

This paper describes the design of fuzzy logic-based controllers as IP modules compatible with the processing systems available in the current families from Xilinx. These modules can be used as standard peripherals connectable to the OPB bus for the processors available in FPGAs, such as MicroBlaze or Power PC. The use of inference techniques based on fuzzy logic allows the development of complex control systems from the linguistic description of the knowledge of an expert operator, without any need to employ mathematical models, and provides good robustness in the face of changing operational conditions
