Stabilization Analysis And Guaranteed Cost Control Of Networked Control System

As a typical application of periodic system, Networked Control System, NCS is developed with the needs of the continuous advancement of communication technology and network technology, automatic control systems, economic and technical control. The advantages of network control system are that the system can achieve resource sharing, distributed control, and intelligent node device makes the system build flexible, low cost, easy to maintain and extend, thus the NCS widely used in equipment manufacturing, process control, marine aerospace and robotics control, and continuous domain, discrete domain and continuous-discrete mixed-domain; study population consisted of linear systems, nonlinear systems and generalized system, also fully reflects the development trend of intelligent network control system, integration, distribution and node. The problem of NCS is:the intervention of the closed loop system network allows the system exists in the information transmission delay time which cannot be ignored the problem of loss of data and clock synchronization difficulties. So NCS is increasingly referred to as the control of the hot areas of research. This article is based on linear matrix inequality and Lyapunov function mainly discussed the stability problems of a class of networked control system, and the guaranteed cost control of the other networked control system.The main structure of this article is organized as follows:Chapter 1 introduces the overview of NCS and its current, as well as the guaranteed cost control of the relevant overview and research of it. Chapter 2 introduces the need prior knowledge and control theory. For example:the networked control systems, the introduction of linear matrix inequalities and the need of Lemma. Chapter 3 is mainly based on observer for a class of networked control its stability analysis. Through the system is discredited to analyze the stability of the system, without regard to the introduction of an observer in the case of system packet loss. Chapter 4 studies a class of uncertain time delay network control system, and its guaranteed cost control analysis. Which does not consider the lost packet to the network control system, introduced uncertainties in the system, the design of dynamic output feedback controllers, the stability of the system is guaranteed and meet certain quadratic performance index. Chapter 5 focus on a class of uncertain time delay network control system guaranteed cost control analysis. Still does not consider the lost packet to the network control system, uncertain delay system with less than one sampling period, introduced uncertainties in the system, the design of dynamic output feedback controllers, the stability of the system is guaranteed and meet certain quadratic performance index.Chapters 6 is the summary of the whole article, and make an outlook for networked control systems as well as networked control system performance in security research.
