A fuzzy system based on the extended Hybrid Fuzzy Boolean Finite State Machine (HFBFSM) model is designed and implemented in a Xilinx Zynq® all programmable System on Chip (SoC). The system allows for a single dominant crisp state and multiple non-dominant states to be activated simultaneously. A method is proposed to calculate the degree of membership of non-dominant states, β, by the distance of defuzzified fuzzy inputs to state transition trigger mechanisms.
The HFB-FSM is was realized by the author using custom logic written in VHDL (Very High Speed Integrated Circuit (VHSIC) Hardware Description Language) in the Programmable Logic (PL) portion of the SoC while one of the application processors provides system control and an Ethernet network interface. The design is flexible and parameterized to simplify and accelerate deployment to new applications.
The thesis first presents the theoretical background followed by a discussion of the detailed design of the custom logic and processor based systems. Detailed simulations are included to support the design material along with discussion of a relevant application.
