Abstract
Using the comparison method, the stability study of the unperturbed motion of a differential system of /b n/ scalar equations with /b m/ known independent first integrals (1<or=/b m/</b n /), is reduced to that of the corresponding solution of a certain reduced system of 8/b n/-/b m/) scalar equations. Some theorems of stability and partial asymptotic stability of the unperturbed motion are given. These results are applied in Mechanics for the stability study of generalized steady motions of non-autonomous holonomic dissipative systems with ignorable coordinates. As an illustration, a concrete example of a stabilization problem by means of an elastic force with time-varying coefficient is given.
