Figure 2: MOR results for Case 1 (w/w0 = 3, l/l0=1.5, T-T0=10), Case 2 (w/w0 = 15, l/l0=7.5, T-T0=50) and Case 3 (w/w0 = 27, l/l0=13.5, T-T0=90­), with w0, l0 and  T0 being the nominal parameter values. (a) The transfer functions (from u1 to vo1) of the RLS-based reduced models (size=10) and the original ones (size=1004). (b) The maximum relative errors of the three cases are about 10-5, 10-6, and 10-8, respectively.
