Practical models and control methods with data packets loss on NCS

Data packets loss is a basic phenomenon of network, and it may affect the system stability in the networked control system (NCS). In this paper, the states and description methods of single data package and multi data packets loss in NCS is put forward, and then an applied compensation and control method is introduced, some of which includes data loss compensator, loss of real time repairing and improving of packet context and self adaptive intelligent control algorithm. The results may be regarded as a main supplement of time-delay NCS. If data package loss problem is treated properly in practical application, it will be sometimes an effective means of increasing system stability.
