The directed transport properties of feedback coupled Brownian ratchets under the effect of external periodic force and load force are investigated. The influence of the coupling strength on the transport properties of coupled system is discussed in detail. It is found that the centre-of-mass mean velocity, the average diffusion coefficient and the energy conversion efficiency of the feedback system can achieve the maximum for the different optimal coupling strength, and the maximum move to right with the increase of the natural length. It implies that the optimal coupling strength and natural length can promote the directed transport and energy conversion efficiency of the feedback ratchets.
Key words: Bioengineering / feedback-control / directed transport / energy conversion efficiency
