Abstract
This paper presents a method of fuzzy gain scheduling for a PID controllerapplied to mean arterial pressure (MAP) regulation during general anesthesia by sodiumnitroprusside (SNP) infusion. A supervising algorithm is used for online updating thefuzzy gain scheduler of the PID controller to act stronger against the body reaction. Anew model based on Slate’s model and Furutani’s ideas was developed for testing thecontroller. Simulation and clinical results in deep hypotensive controls at 40mmHg onpigs indicate the safety and stability of designed controller.
