A fuzzy blood pressure controller

Abstract

An automatic blood-pressure controller yielding satisfactory results in simulation has been constructed using fuzzy set theory. This prototype controller is not adaptive and is therefore not intended for closed-loop control in surgery. However, the fuzzy control approach is very well suited to closed-loop control in complex biomedical problems. Further study is currently under way in the area of adaptive fuzzy control, in order to manage wide variations in patients' drug responses (e.g. drug sensitivity and time delay).< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
