Test-case 1: original, desired, and modified system natural frequencies.
| | | Original system | Desired value | Modified system without robustness (method [28]) | Modified system with robustness (proposed method) |
| | ωp,1 (Hz) | 21.87 | 25.00 | 25.00 | 25.00 | | ωp,2 (Hz) | 32.13 | — | 32.64 | 34.33 | | ωp,3 (Hz) | 42.48 | — | 41.28 | 36.84 | | ωp,4 (Hz) | 52.44 | — | 50.56 | 47.05 | | ωp,5 (Hz) | 64.36 | — | 58.31 | 50.91 |
