    The robust servo control of a model-based biomedical application, namely the glucose-insulin control of diabetes patients under intensive care, is presented in the paper. The synthesis and analysis is based on a modified two compartment Bergman model and realized with a two degree of freedom controller structure permitting to assure insulin tracking. The augmented Δ − P − K structure is described with the necessary weighting functions. A non-conservative complex μ-synthesis method is applied. Using the controller, not only the robust stability is met under multiplicative uncertainty, but also the nominal performance i.e. the disturbance rejection is fulfilled. Food (sugar) intake is considered as disturbance. Closed loop simulation results are edged for optimizing the insulin amount.
