Table 7
Test-case 2: original, desired, and modified antiresonance frequencies of h12(jω).
| | | Original system | Desired value | Modified system without robustness (method [28]) | Modified system with robustness (proposed method) |
| | ωz,1 (Hz) | 24.68 | — | 24.08 | 28.99 | | ωz,2 (Hz) | 42.42 | 40.00 | 40.00 | 40.00 | | ωz,3 (Hz) | 64.36 | — | 63.04 | 63.23 |
