本文在有限的信息存在下分析了因果闭环连续时间系统。假设可以将外源信号建模为随机过程，则获得了相互信息率不平等，可以将其视为用于固定过程的扩展Bode-Type公式。然后，分析了生成的Bode的积分不等式的紧密度，以分析线性时间不变的闭环。在开发的框架内，我们考虑控制控制相互作用并分析基本的基本局限性。
This paper analyzes causal closed-loop continuous-time systems in the presence of limited information. Assuming that the exogenous signals can be modeled as a stochastic process, a mutual information rate inequality is obtained that can be viewed as an extended Bode-type formula for stationary processes. The tightness of the resulting Bode's integral inequality is then analyzed for the linear time invariant closed loops. Within the developed framework we consider the control-communication interplay and analyze the underlying fundamental limitations.
