Abstract:

This paper serves as a tutorial paper for a new area of research in control systems, namely, quantized feedback control and

estimation. This area is motivated by the increasing need of incorporating communication networks in a control system. In such a

framework, feedback information needs to be transmitted over a digital network, which results in a number of new challenges for

estimation and control design. The focus of this paper is to introduce a number of recent results on the design of quantizers

for the purposes of control design and state estimation. uantized feedback control, networked control, quantized estimation,

robust control.

Key words: networked control, quantized feedback control, quantized estimation, quantization theory, separation principle1Introduction
