English summary) Zbl 1399.93100 Control Theory Appl. 34, No. 9, 1195-1200 (2017). Summary: In this paper, the tracking performance limitations of linear time-invariant networked control systems (NCSs) with two-channel constraints for random reference signal is investigated. Network communication contains channel noise and communication bandwidth. The plant is considered as a minimum phase and unstable system, and the system has distinct multiple non-minimum phase zero and distinct multiple unstable pole. For the cases of up-link and down-link channel with limited bandwidth and additive white Gaussian noise (AWGN) effect, the optimal tracking performance for networked control systems is obtained by adopting two-degree controllers and Youla-parametric method based on frequency domain. The results show that the optimal tracking performance depends on structural characteristics of the plant (such as the non-minimum phase zeros, unstable poles and gain at all frequencies of the given plant), reference input signal, network characteristics (communication bandwidth, the statistical characteristics of AWGN). Finally, a typical example is given to illustrate the theoretical results.
