Considering the uncertain time-delay of networked control systems, the networked control systems is modeled as an uncertain discrete system with delay firstly, using Stability theory of Lyapunov and linear matrix inequality approach, discussed the system stability. Combining with a given quadratic performance index, a necessary and sufficient condition for the existence of guaranteed performance controls...
The Ethernet has gotten extensive application in industrial networked control system at present. In the NCS, the main factor which affects the performance and stability of the system is the introduce of the conflict among the network nodes. We use the queuing theory to analyze this problem, which deduces the sending delay and queuing delay which caused by the conflict among the network nodes. Then...
