Research on quantization errors of stability for model-based networked control system

In this paper, stability conditions for MB-NCS under popular quantization schemes are derived. Static quantizers have quantization schemes that do not vary with time, that is the error between the quantized value and the real value does not depend on time. Two quantizers of this type are considered: the Uniform Quantizer with a constant maximum quantization error; and the Logarithmic Quantizer with a maximum quantization error that is proportional to the norm of the quantized value. Dynamic Quantizers are introduced, these quantizers dynamically adjust their quantization regions to compensate for uncertainties while giving a quantization error that shrinks with time.
