The trends set by the Internet of Things (IoT) are pushing us to understand the interactions between communication, computation and control in systems. This talk will discuss simple models that can provide insights on the “informational” limits on control of high-performance systems with uncertain system parameters that are difficult to track.
We will define a novel notion of “control capacity,” as the fundamental limit on the ability of a noisy actuator to control a system. Control capacity builds on the traditional notion of communication capacity in information theory. The formulation provides an information-theoretic perspective that allows us to understand the value of side information in the context of control systems.
If time permits, the talk will also touch upon the development of communication protocols for low-latency high-reliability control over wireless, which are necessary for the IoT vision of the future.
