我们计算了反馈控制系统由于控制器的重复操作而产生的熵约化。这是建立这些系统的热力学，特别是麦克斯韦恶魔的热力学所缺乏的要素。我们通过推导可以从等温反馈控制系统中提取的最大功来说明我们的一般结果的一些结果。作为一个实例，我们最后研究了一个执行等温信息驱动的粒子泵浦的简单系统。
We compute the entropy reduction in feedback controlled systems due to the repeated operation of the controller. This was the lacking ingredient to establish the thermodynamics of these systems, and in particular of Maxwell's demons. We illustrate some of the consequences of our general results by deriving the maximum work that can be extracted from isothermal feedback controlled systems. As a case example, we finally study a simple system that performs an isothermal information-fueled particle pumping.
