Equation set of a class of optimal control problems is deduced in quantum mechanical systems based on the variational approach. Furthermore, an on-off variable metric numerical iterative arithmetic with optimized search step length is used to solve such an optimal problem. Finally, some simulation experiments on a spin-1/2 particle system are done. Experimental results demonstrate the validity of the method proposed. At the same time, the effectiveness of the system control under different parameters in the performance index is analyzed.
