Optimal Tracking and Regulation Performance of Networked Control Systems With Time Delay and Input Quantization

Abstract

This technical note investigates the optimal tracking and regulation performance of networked control systems (NCSs) with time delay and input quantization. To this end, advanced trade-off performance indices for multi-input multi-output (MIMO) systems are firstly proposed, aiming to identify new design constraints beyond those imposed by known limitations, such as unstable poles (UPs) and non-minimum phase zeros (NMPZs). Then, some analytical expressions of optimal tracking and regulation performance are derived using frequency-domain analysis and two-degree-of-freedom (TDOF) control techniques. The results demonstrate that the tracking and regulation performance of NCSs is influenced by the locations and directions of the NMPZs and UPs of the plant, network-induced time delays, quantization dead zones, and quantization densities. Finally, the validity of the conclusions drawn in this study is confirmed through simulation examples.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
