摘要
针对网络控制系统中存在的网络诱导时延问题,提出了一种系统能控能观性分析的方法。通过对不同驱动方式下网络控制系统信号传输机理的分析,得出驱动方式对系统的影响体现在被控对象的输入上的结论。基于事件驱动方式下的多输入长时延的网络控制系统模型,通过对系统中网络诱导时延环节的处理和状态增广,得到能控能观性的充要条件。
A controllability and observability analysis method is proposed for the problem of network-induced time delays in networked control systems. After signal transfer mechanism in different driving modes of networked control systems is analyzed, the conclusion is given that driving modes influence systems on plants' inputs. Based on the model of event-driven multi-input networked control systems with long network-induced time delays, sufficient and necessary conditions for controllability and observability analysis are presented by time delays' disposal and state-augment.
