This paper theoretically deals with the self-excited vibrations of a rotating Mindlin circular plate subjected to a concentrated frictional force as a function of relative slip velocity exerted on its outer circumference, when the circular plate has some imperfections .As typical of the imperfections, the authors considered the additional masses for the circular plate without imperfection. It turned out from the method of multiple scales that (1) only single modes are stable, (2) the imperfection has a tendency to suppress the occurrence of the self-excited vibrations in the same manner as the rotating speed and the optimal arrangement of the additional masses to control the self-excited vibrations is obtained for each mode, and (3) the resulting vibration shows the waveforms with beats.
