Design of Fuzzy Controller for Patients in Operation Theater
In recent days, technology develops for the application in versatile fields. Mostly, soft computing techniques enhance the technological aspects in the field of engineering and medicine. In this paper, fuzzy logic-based controller is designed to support the surgeons in operation theater. At the time of surgical operation, the anatomical parameters are to be well controlled especially blood sugar and blood pressure. It provides intelligent control applied in the field of medicine. A fuzzy logic controller for mean arterial pressure (MAP) control is considered as limit for the depth of anesthesia. The fuzzy membership functions and the linguistic rules using fuzzy logic are developed for the design. The adaptive neuro-fuzzy inference system (ANFIS) has been applied for implementation and simulation of the controller. The performance of the fuzzy logic based PID controller is found excellent in computer simulations with respect to noise tolerance, tracking ability. Simulation result is shown that the exceptional regulation of blood pressure around set-point targets is realized with application of fuzzy logic controller.
