Figure 3
Bode magnitude plots of the linearized difference system of the two models with output ( A , I , R *), I , and R *. The difference between the two models' R* values is marginal compared to the I values. The L2-gains for outputs (A, I, R*), I, and R* are 0.4766, 0.4762, and 0.02038, respectively. At this resolution one cannot see a difference between the cases when the output is the full state (A, I, R*) or I only. The shape of the Bode magnitude plot for single outputs I and R* is similar, with only slightly different critical frequencies (0.4472 and 0.3853, respectively). The critical frequency corresponding to completely observed state is 0.4470.
