Chapter 3 Observer-Based Output-Feedback Stabilization for CPSs with Quantized Inputs
3.1 Introduction
In CPSs, because of the limited bandwidth of the network, signals are always quantized before being communicated. In recent years, signal quantization in feedback control system has received a great deal of attention, which is mainly due to the widespread use in control systems of digital computers that employ finite-precision arithmetic [40]. In recent studies, quantizers are usually regarded as information coders, and the most important problem is how much information is required to be communicated by the quantizer in order to achieve a certain performance objective of the closed-loop system. By following ...
