Abstract

The variational approach for statement and solution of the nonlinear synthesis problems according to the amplitude characteristics is examined. The numerical solution of problems is realized by the methods of successive approximations, which are used for solving the corresponding Euler´s equations or the direct optimization of functionals. The results of simulation confirm the effectiveness of the approach proposed.
