MAMDANI-TYPE FUZZY CONTROLLER TO DETERMINE BLOOD PRESSURE LEVELS BY REFLECTION PPG

This document presents the design of a fuzzy control system applying photoplethysmography techniques to generate input data and Mamdani-type logic for its processing generation output values, through which blood pressure levels can be indicated based on parameters recommended by medical area an adult person. The integral includes acquisition signals, obtained reflection technique, means optical coupling between IR light-emitting diodes photo receptors, allow flow current proportional amount reflected light blood, is related level cardiac cavities, derived from systolic diastolic stages cycle. was designed with two inputs one 5 triangular membership functions each using hardware description language (VHDL), fuzzification, inference, aggregation defuzzification were COSAA method. response values ​​obtained Test Bench tool ISE Design suite compared theoretical ​​and Fuzzy Logic Designer Matlab, results showed excellent approximation.
