Due to the random and uncertain characteristic of networked induced factors, the performance of networked control systems is seriously affected, which is not merely degraded but also cause system instability. In this paper, a newly enhanced control scheme with an improved smith predictor is proposed to solve the issues caused by the complex and uncertain network conditions. A database is integrated...
In this paper, the basic principle of Single Frequency Network (SFN) for DTMB system is introduced, and a new SFN scheme based on Coordinated Universal Time (UTC) is proposed. Compared with the traditional SFN for DTMB, the proposed scheme has two advantages: the maximum propagation delay is not limited to 1 second; reference time information is distributed by IEEE1588v2 standard instead of respective...
In order to efficiently support the Machine-to- Machine (M2M) applications, a new amendment of Wi-Fi standard known as IEEE 802.11ah is introduced. In 802.11ah, several enhanced MAC features are added so as to provide scalability for a large number of stations as well as to reduce the energy consumption compared with the existing Wi-Fi technologies. In this paper, a selected set of 802.11ah MAC features...
Research on the problem of the control and synchronization for a class of continuous-time chaos system with unknown parameter and time-delayed property (CTCS-UP-TP) was investigated. An effective synchronization controlling algorithm combined variable structure control with adaptive parameter estimation was given under the certain hypothetical conditions. At the same time, the realizing principle...
This paper carried out the research on the problem of control and synchronization of the chaotic system. The controller based on linear couple rules and the theory of parameters estimation was designed for the continuous-time chaos system with unknown parameter and delayed-time property (CTCS-UP-DTP). Meanwhile, the asymptotic stability of the control and synchronization continuous-time chaos system...
The research on the problem of control and synchronization of the chaotic system would be carried out in this paper. The simple and reliable controller based on linear coupling rules and the theory of parameters estimation was designed, for the continuous-time chaos system with unknown parameter and delayed-time property(CTCS-UP-DTP). At the same time, the asymptotic stability of the control and synchronization...
