摘要

Studying the performance limitations of communication-constrained networked control systems (NCSs) is of utmost significance and poses a considerable challenge from an academic standpoint. This article investigates the tracking performance limitations (TPL) and regulation performance limitations (RPL) of a NCS with communication constraints in the network channel, such as network-induced delay, packet loss, additive non-zero mean noise, finite bandwidth, and encoding-decoding constraints. Explicit expressions for the TPL and RPL of NCS are derived using Youla parameterization method-based two-degree-of-freedom control techniques, various decomposition techniques, and related statistical theory. The results show that in addition to the essential characteristics of the plant such as nonminimum phase zeros and unstable poles, communication constraints will also deteriorate the control performance of the system. Finally, we apply the theoretical results to an inverted pendulum system and two-input and two-output plant through numerical simulation, and the correctness of the results is verified.
