Extensive testing and use of a nonadaptive automated blood pressure controller has proved the safety and efficiency of closed-loop regulation of hypertension. However, the large range of patient characteristics suggests the need for an adaptive algorithm. Adaptive control was implemented with parallel least-squares estimation routines to adapt to patient gain and to desensitize the controller to the...
The Control Advance Moving Average Controller, a modification of the Minimum Variance Self-Tuning Controller, Was used to simultaneously control Mean Arterial Pressure and Cardiac Output in anesthetized dogs. By varying the infusion of sodium nitroprusside and dobutamine the controller successfully lowered the mean arterial pressure and raised the cardiac output to preset setpoints.
Although various control schemes have been successful in controlling mean arterial blood pressure by infusing a vasoactive drug, the simultaneous control of cardiac output and blood pressure by multiple drug infusion has to-date received little attention. To this effect, this paper describes the design of an automated multiple drug delivery system. The proposed computer-based controller combines supervisory...
