This microprocessor based drug infusion control system is intended to aid doctors and nurses in the care of critically ill cardiac patients. The patient's arterial blood pressure is monitored and the infusion rate of the vasodilator sodium nitroprusside is regulated based on a model reference adaptive control algorithm. The algorithm employs a reference model to approximate the patient drug response. The reference model output is compared with the patient blood pressure change and the...
Show moreThis microprocessor based drug infusion control system is intended to aid doctors and nurses in the care of critically ill cardiac patients. The patient's arterial blood pressure is monitored and the infusion rate of the vasodilator sodium nitroprusside is regulated based on a model reference adaptive control algorithm. The algorithm employs a reference model to approximate the patient drug response. The reference model output is compared with the patient blood pressure change and the adaptive controller parameters are changed bringing the patient drug response in closer agreement with the reference model. Drug infusion is digitally controlled by a microprocessor based system and employs a stepper motor driven peristaltic pump. Simulation studies have validated the system. Animal experiments and clinical studies will be conducted later.

Abstract/Description

Several adaptive controllers have been designed to control the infusion of the drug sodium nitroprusside for the purpose of reducing high blood pressure in post surgical patients. Most of these controllers have not considered one or more factors of the controlled system including the stochastic background noise present in the patients, the time varying nature of the patient, and the constraints imposed on the control input and system output. This thesis presents a model reference adaptive...
Show moreSeveral adaptive controllers have been designed to control the infusion of the drug sodium nitroprusside for the purpose of reducing high blood pressure in post surgical patients. Most of these controllers have not considered one or more factors of the controlled system including the stochastic background noise present in the patients, the time varying nature of the patient, and the constraints imposed on the control input and system output. This thesis presents a model reference adaptive controller which takes into account all of these factors. Through simulations on a personal computer, the robustness of the controller is demonstrated in the presence of noise, time varying parameters, and deterministic disturbances. Furthermore, this performance is achieved without requiring any prior knowledge of the system delay.
