The Stability

The current study of network control stability system has become a very hot topic, the stability conditions of network control systems have also carried out the relevant research on double delay discrete model, its main target to the current actual situation, which carries out the related stability for network control systems with state time-delay. This paper uses the relevant stability theory, the sufficient condition of network control system stability are described under the time-delay discrete model, on the basis of relevant transformation, completing the evaluation for the network control system stability condition of double delay discrete model. Finally, through the relevant data, to carry on its effectiveness validated. The method has certain reference significance for the stability study of similar system, and provides a theoretical reference for the research on this problem.

The Stability

Networked Control System (NCS) is a class of feedback control system forming a closed loop through the communication network. Due to the nodes conflicts, poor network stability, limited data bandwidth and other uncontrollable factors in the transmission, network-induced delay is the main factor reducing system performance and stability. Studying the state feedback rules of Long Delay Network Control system, the author proposes Stability and stabilization method for Random Long Delay Network Control. The method models random long delay closed-loop network control system, compensate the delay and complete the network stability and stabilization. Finally, a numerical example is given to verify the validity of the conclusion.

Improving network control system---NCS reliability and safety has important practical significance because NCS is a hot research subject in these years. Fault diagnosis methods are researched in this paper according to NCS with long-time delay and data packet loss. Firstly, given a NCS with long-time delay, a state observer is structured. Secondly, make the state estimation error equation equivalent to an asynchronous dynamical system having event incidence constraint according to whether the system having data packets loss. The problem of fault diagnosis is converted to filtering problem through structuring filtering residual system based on the observer, then giving a corresponding filter designing algorithm. The designed fault diagnosis filter system not only make sure the stability of the closed loop system but also make the residual systems norm less than given reduction level. Finally, the simulation results prove that the algorithm can diagnose faults effectively.
