Application of Dragonfly Algorithm-Based Interval Type-2 Fuzzy Logic Closed-Loop Control System to Regulate the Mean Arterial Blood Pressure

Globally, the importance of closed-loop regulated drug delivery has been realized in the field of healthcare systems during pandemic times. The automatic control drug delivery system not only reduces the burden of the physicians but also infuses only the required amount of drug to the patient to avoid the situations like underdosing or overdosing. Therefore, in this work, a dragonfly algorithm (DFA)-based interval type-2 fuzzy logic control proportional + integral derivative control (IT2-FLC-P + ID) has been implemented to provide automatic regulation of a drug to maintain the mean arterial blood pressure within the prescribed limits. Here, the DFA is used to find out the best controller values to design an efficient control scheme. Furthermore, the performance of the proposed automatic control system is investigated with its classical type-1 FLC control approach. The effects of sudden fluctuations or disturbances are also included in the closed-loop drug delivery system in order to find out the controller’s effectiveness. Overall, the automatic control of drug delivery systems for human physiological parameters is an essential requirement and needs attention.
