Nonlinear active systems,n Chapters 3 and 4, see also . It was shown that the nonlinearity of elastic restoring characteristics and especially the presence of elastic and rigid stops lead to undesirable resonances. To suppress them, one should increase either the clearance or the system dissipation. In the present Chapt
