A fuzzy logic controller for the application of skin pressure

A new defuzzification method known as Sparus, has shown some promise in testing, but has not been utilized in a real-world environment. In order to test this new design of a FLC (fuzzy logic controller), an experimental medical research device for testing pressure induced hyperemia was modified to utilize fuzzy logic. The FLC directly controls a regulator that uses air to apply direct pressure via a pneumatic piston to the tissue of a human subject. The device also encompasses components such as a blood perfusion monitor and analog to digital converters for data collection and pneumatic valves and sensors for controlling air flow. As the paper shows, the utilization of a FLC has greatly improved the performance and accuracy of this experimental device and that this new defuzzification method can be effectively deployed in real-world scenarios.
