有一个越来越多的兴趣在研究控制系统采用多个传感器和执行器的地理分布。通信是这些分布式和网络化控制系统的重要组成部分。因此，需要理解分布式系统的控制组件和通信组件之间的交互。在本文中，我们制定了一个控制问题的通信通道连接传感器的控制器。我们的任务包括设计信道编码器和信道解码器沿着的控制器，以实现不同的控制目标。我们提供了上界和下界的信道速率需要实现这些不同的控制目标。在许多情况下，这些边界是紧的。在这样做时，我们的“信息复杂性”的不同控制目标的特点。
There is an increasing interest in studying control systems employing multiple sensors and actuators that are geographically distributed. Communication is an important component of these distributed and networked control systems. Hence, there is a need to understand the interactions between the control components and the communication components of the distributed system. In this paper, we formulate a control problem with a communication channel connecting the sensor to the controller. Our task involves designing the channel encoder and channel decoder along with the controller to achieve different control objectives. We provide upper and lower bounds on the channel rate required to achieve these different control objectives. In many cases, these bounds are tight. In doing so, we characterize the "information complexity" of different control objectives.
