Abstract: Firstly the dynamic characteristic of geomagnetic intensity in a circular is analyzed.Then the magnetic dipoles produced by magnetorquer are expanded in Fourier series. On the basis of the sum of unloaded angular momentum,the magnetic dipoles are figured out according to the theory of optimal control.The stability of control low and simulations are given,which shows the method is simple and the energy can be saved very much.
