Neha Bahal, Shamim Akhter . VHDL Implementaion for Fuzzy Logic Temperature Controller. International Journal of Computer Applications. 98, 22 ( July 2014), 31-34. DOI=10.5120/17317-7730
Abstract
This paper, illustrates an implementation of fuzzy logic based temperature controller using VHDL in Modelsim 6. 4. . Nowadays fuzzy controller designs have become valuable in large number of applications. There are three basic steps for fuzzy logic controller i. e fuzzification of inputs, defuzzification of outputs, and rule base. In this designed temperature controller there are 2-inputs, 1-output and 5-membership functions. According to the 2 inputs( temperature and humidity), the output (speed of air conditioner) is controlled based on relation between the fuzzy set (low, med, high, dry, moist, wet) of the 2 input variables.
