Research On Characteristics Of The Wireless Wireless Control System

The networked control systems are generated through the recombination of computer, communication and control technology. In recent years, the networked control systems move a big step towards networking, highly integration, then making the network control technology into a new era. Having a small cost, more convenient installation and maintenance, share information, relatively easy expansion and any other advantages, the networked control systems have been widely applied to many aspects, such as industrial automation, aerospace navigation, building systems, urban transport. Compared with Wired Networked Control Systems, Wireless networked Control Systems which derive from Wired Networked Control Systems have more rich unique advantages, which have been applied widely. However, it also has many problems which had not appeared,such as: network-induced delay, packet loss, packet timing confusion and so on.Conventional control theories which have to be re-examined can play a role in the wireless networked control systems. The paper studies the design of the modeling and controller in the wireless network systems in order to solve the problems which exist in the Wireless networked Control Systems.First, in order to better understand the wireless networked control systems,we have read a great deal of literature, we unfold the narrative aiming at the problems and development achievements of the wireless networked control systems, Further study to build the wireless networked control systems model,modeling under the same or smaller than the delay of one sampling period is large and delay than the case of one sampling period.What's more, the wireless networked control systems for the Rescue Robot presence of various data latency, packet loss and other phenomena, under the condition of delays in data, study the robot wireless networked control systemssecurity problems, a simulation can proof guaranteed cost control strategy is feasible.Finally, aiming at the special case of voltage system, built the network secondary voltage control model which has uncertain network delay, packet loss and confusion, using variance control theory and fault-tolerant design of the secondary voltage control theory variance fault-tolerant controller to ensure effectively control the stability of the secondary voltage in case of sensor failure...
