| Summary: | This work considers the problem of automatically controlling the glucose level in insulin dependent diabetes mellitus
(IDDM) patients. The objective is to include several important and practical issues in the design: model uncertainty, time
variations, nonlinearities, measurement noise, actuator delay and saturation, and real time implementation. These are fundamental
issues to be solved in a device implementing this control. Two time-varying control procedures have been proposed which take
into consideration all of them: linear parameter varying (LPV) and unfalsified control (UC). The controllers are implemented
with low-order dynamics that adapt continuously according to the glucose levels measured in real time in one case (LPV) and
by controller switching based on the actual performance in the other case (UC). Both controllers have performed adequately
under all these practical restrictions, and a discussion on pros and cons of each method is presented at the end. |
