| Abstract: | The optimal vibration control of structure, under complex force excitation is studied in the paper. The approach is based on the signal processing theory and the vibration characteristic analysis of the ship main engine. Simulation results are given, considering the ship as a simply supported beam, the influences of the frequency estimation accuracy and of the system model error on the control quality are discussed. |
