Design and synthesis of temperature controller using fuzzy for industrial application (original) (raw)
This paper describes the VHDL modeling of temperature controller based on fuzzy logic intended for industrial application. The system is built of four major modules called fuzzification, inference, implication and defuzzification. The composition method selected for the fuzzy model is the Max-Min composition while the Mamdani Min operator was chosen as the implication method. Each module is modeled individually using behavioral VHDL and combined using structural VHDL. Following a successful VHDL coding, timing analysis was done verifying the functionalities of the algorithm with all simulated conditions. Simulation results show that the model has been tested successfully. The verified model of VHDL has synthesized using synthesis tool to get gate levels. The inferred maximum operating frequency is 5MHz with a critical path of 199.3ns.
