This study has originated from the discussion following the adress by Prof. Ichikawa of Nagoya University before the 2nd Annual Meeting of the Society of Instrument and Control Engineers held on the 2nd, October, 1963. Since then, while discussions on his succeeding three adresses on similar problems continued, the author has been trying to find the suitable forms of the asymptotic method favourbly applied to various nonlinear control systems. Special features of automatic control systems consist in the situation that damping of considerable amount is present and many essentially nonlinear elements are frequently included in them. To cope with this situation, the generating solution as the starting point of applying the asymptotic method should be carefully selected. The good selection enables us, already at the first approximation, to obtain the accuracy corresponding to that obtained by the second approximation of the ordinary form of the asymptotic method.
