The invention discloses an online enhancement control method for improving transverse and lateral stability of a plane-symmetric high-speed aircraft. The method comprises the following steps: S1, designing a baseline controller; s2, designing an online identification algorithm of a transverse and lateral coupling dynamic coefficient; and S3, designing an identification coordination mechanism based on adaptive gain adjustment. The method can solve the problem that the horizontal and lateral control of the plane-symmetric high-speed aircraft has a small range of adaptation to uncertainty, and on the basis of a nonlinear dynamic inverse simplified control model, by designing a mutual coordination mechanism of'parameter identification based on bilinear transformation and a non-overlapping sliding window 'and'adaptive gain adjustment', when the uncertainty is small, the lateral and lateral control of the plane-symmetric high-speed aircraft can be realized, and the lateral and lateral control of the plane-symmetric
