Abstract


Network Control System ( Networked Control System ) is an interdisciplinary communication works (including wireline communications and wireless communications ) and control engineering, engineering . The Networked Control is the objective needs of complex system control and remote control system . In recent years, the study of the network control system has gradually become a hot research topic , many scholars to expand the traditional control theory to the network control system , and have achieved a certain amount of research , but there are still many problems to be solved . This paper studies a series of problems in the network control systems , and carried out innovative work as follows : (1) starting from the actual system , containing both the sensor - controller delay and controller - actuator delay network modeling , analysis, so that the study has a fairly realistic background , more comprehensive and objective . (2) In this paper, the network control system prevalent in the random latency issues , Markov transition theory analysis system modeling, constructing Lyapunov equation , under certain conditions , to meet the robust stochastic stability conditions . (3 ) the characteristics of the network control system , the design of a class of dynamic feedback controller to achieve the control of the system , allowing the system to achieve the desired performance ; full-dimensional observer design of the network control system , the state of the system To achieve the ideal observation of the effect . (4) is given the LMI approach each control conditions , in particular , a class of non- strict LMI , given a class of iterative algorithm . Finally, the simulation proved the correctness of the results obtained in the thesis .
