摘要：
We presented a detailed investigation on the movement of two-headed Brownian motors in an asymmetric potential under a feedback control.By numerical simulations the direct current is obtained.The current is periodic in the initial length of spring.There is an optimal value of the spring constant.And the dependence of the current on the opposing force is reversed.Then we found that when the change of the temperature and the opposing force have optimal values,the Brownian motors can also obtain the optimal efficiency.
