The control time is supposed to be relative large, the averaged system is obtained by using of the averaging theorem in the quantum system. The control field of averaged system is designed by classical optimal control theorem, then analytic expression for the control field is acquired within optimal energy. As a result, the normal iterative solution of a two-point boundary value problem is avoided by the use of averaging optimal control. At last, the method is used to a three-level quantum system. The some analysis are given according to the simulation test results.
