Control over communication networks

This chapter presents a case study of constrained control and estimation in the area of networked control. Networked control is a term used to describe control actions that take place over a networked communication system. A key issue that arises in this context is the need to quantise data so that it can be communicated over the network. Quantisation occurs in both time and space and is needed on bot the "up-link" (between the plant and the control computer) and the "down-link" (between the control computer and the plant). In this chapter we show how this problem can be formulated in the framework of constrained control and estimation
