tailieunhanh - A note on nonlinear systems with different degrees of excitations

In this note an approximate solution of a differential equation of special form which is close to the Liapunoff type is given. This solution is proportional to the small parameter e. | Journal of Mechanics, NCNST of Vietnam T. XVI, 1994, No 3 (47 - 49) A NOTE ON NONLINEAR SYSTEMS WITH DIFFERENT DEGREES OF EXCITATIONS NGUYEN VAN DAO Institute of Mechanics, NCNST of Vietnam In this note an approximate solution of a differential equation of special form which is close to the Liapunoff type is given. This solution is proportional tO the small parameter e. 1. DIFFERENTIAL EQUATION AND ITS APPROXIMATE SOLUTION Let us consider a nonlinear system described by the differential equation (Ll) where w, /, (3, h, v are constants, e is a small positive parameter, f(
