Effect of transmission delay and clock synchronization on networked control systems
传输时延和时钟同步对以太网控制系统的影响

A new model of Markovian jump discrete-time networked control systems is proposed by considering the effect of the packet transmission delay and the precision of clock synchronization on the networked control systems. The stability conditions for the system with the transmission delay and the clock synchronization are developed. A network control systems(NCS) based on Ethernet-plant-automation(EPA) without data packet dropout is modeled. An algorithm is developed for determining the shortest communication macro cycle for a stable EPA system.
