Dynamic Rule-Based Algorithm to Tune Insulin-on-Board Constraints for a Hybrid Artificial Pancreas System

Figure 3

Operation of the dynamic rule-based algorithm during a postprandial period. Note that, after the meal (consumed at 07:30 and represented by the green triangle), the algorithm deemed necessary to increase because BG levels were above . (a) BG measurements in mg/dl. (b) Insulin delivery. (c) The conditioned reference signal . (d) Estimation of IOB levels and the constraint .
