The aim of this paper is to present the new method for obtaining the semi-active suboptimal control strategy, used for the purpose of vibration reduction in mechanical systems. The method is dedicated to systems where vibrations are of a periodic type. Generally, many semi-active control strategies have been developed up to date, but it seems that none of them are applied directly to the problem of mechanical systems suffering from disadvantageous, periodical vibrations. Probably, the reason why there were no such attempts in the past is that the semi-active vibration damping methods most often were used in situations where systems experience a finite time transient excitation, like for example seismic activity. In a case of systems experiencing repeatable (periodic), steady-state vibrations, such as machines or vehicles working at their nominal conditions, the common approach was to use the passive methods rather than the semi-active ones. This situation is changing nowadays and attempts of using semi-active methods to attenuate the disadvantageous steady state vibrations in machines and vehicles are becoming more common and successful. Therefore, there has been observed a surge in developing of the general purpose methods for determination of the optimal control strategies for such applications. The described method aspires to be the one of possible alternatives.
