JTG/IEEE IT Society Summer School on Information Theory, Signal Processing, Communications and Networks, IIT Bombay, 2-5 July, 2018 Event-triggered control under limited and unreliable communication Pavan Tallapragada IISc, Bangalore Abstract: Networked control systems (NCS) are systems in which the signals for feedback control are communicated over a communication channel. In particular, the communication resources are assumed to be constrained in some manner. This necessitates an integrated approach to control and communication. Thus, the notion of NCS is an important and a fundamental abstraction of many cyber physical systems. NCS operated by digital computers using digital communication naturally induce sampling and quantization of feedback and control signals. Time-triggered (periodic) sampling and uniform static quantization are still the de facto standards in practice. However, such sampling and quantization methods are often very conservative and indeed it is difficult to provide analytical guarantees for them except in very simple scenarios. Faced with this, in the last decade, a major theme in NCS has emerged - that of event-triggered control, wherein sampling and quantization are treated as online decision variables rather than offline parameters. This allows for efficient use of communication resources with provable guarantees for a wide array of problems. In this talk, I will give an overview of some of our recent results in this theme in the context of limited and unreliable communication.
