The paper presents a theoretical method for determining the optimal correction to be in-troduced in a mechanical system. The active control of harmonic vibrations may be achie-ved by applying a control unit which ought to reduce the vibration amplitude of the selec-ted elements of the system. The proposed method makes it possible to determine the con-troller parameters which provide an optimum value of the chosen quality index. This crite-rion includes the reduction of weighted amplitudes of the elements on the one hand, andminimizes energy of the control signal on the other. The described method is suitable fordetermination of an optimum controller of turbine rotor vibrations caused by bearing oil whip, bearing oilwhirl or aerodynamic forces. For the case of rotor self-excited vibrations of aerodynamic type the linearmodel of excitations was compared with the neural network method
