| Abstract: | 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.
