摘      要：In this paper,we study the global disturbance rejection problem of nonlinear systems in lower triangular form with unknown *** conditions are established *** the convergence problem of an estimated unknown parameter vector to the true parameter vector is ***,the theoretical result is applied to solve the disturbance rejection problem of the controlled uncertain Duffing’s system subject to a sinusoidal disturbance with unknown amplitude and unknown frequency.
