摘要:

本文聚焦于一类具有双通道约束的网络化控制系统(NCSs)的跟踪性能限制。在通信通道中,考虑了带宽、能量约束和加性有色高斯噪声(ACGN)的同时影响。在系统中,考虑了非最小零点和不稳定极点;多重复零点和极点也适用。为了获得最优性能,采用双参数控制器。理论结果表明,最优跟踪性能受非最小相位零点、不稳定极点、给定系统的所有频率增益以及NCSs的参考输入信号影响。此外,性能限制还受带宽限制、加性有色高斯噪声以及非最小相位零点和不稳定极点的相应倍数影响。此外,在确保系统稳定性和获取系统性能限制的条件下,给出了通道最小输入功率约束。最后,通过仿真示例来说明理论结果。

英文摘要:

This paper focuses on the tracking performance limitation for a class of networked control systems(NCSs) with two-channel constraints. In communication channels, we consider bandwidth, energy constraints and additive colored Gaussian noise(ACGN) simultaneously. In plant, non-minimal zeros and unstable poles are considered; multi-repeated zeros and poles are also applicable. To obtain the optimal performance, the two-parameter controller is adopted. The theoretical results show that the optimal tracking performance is influenced by the non-minimum phase zeros, unstable poles, gain at all frequencies of the given plant, and the reference input signal for NCSs. Moreover, the performance limitation is also affected by the limited bandwidth, additive colored Gaussian noise, and the corresponding multiples for the non-minimum phase zeros and unstable poles. Additionally, the channel minimal input power constraints are given under the condition ensuring the stability of the system and acquiring system performance limitation. Finally, simulation examples are given to illustrate the theoretical results.
