Computer Controlled Systems: Theory and Design

Industrial information integration—A literature review 2006–2015

Due to the constraint of network bandwidth and the conflict of the data,the transmitted time-delay inevitably exists in the Networked Control System(NCS),which is called the network-induced delay.And it is the main problem that can degrade the performance of the control system and even destabilize the system.This paper discusses a linear networked control system model with uncertain parameters and presents the sufficient condition for the stability.The Razumikhin and Laypunov theorems are employed to investigate the problem and obtain the maximal transmitted time-delay.The simulation proved the validity of the conclusion.

Stability Analysis of Networked Control System

Radio Frequency Identification (RFID) facilitates automatic identification of items using radio-waves. This technology albeit initially intro- duced in the 1940s and 1950s, has seen a drastic in- crease in the number of applications and implemen- tations in the recent years. This work aims to review some of the current developments in this field and to develop a taxonomic framework to classify literature which will facilitate quick content analysis and iden- tify future direction of research.

RFID Technology: A Review of its Applications

Industrial information integration – An emerging subject in industrialization and informatization process

Real-time production information is important to enterprise for improving management. Therefore, the RFID technology can be used in production to obtain real-time information, which is integrated into the manufacturing execution system, and the decision of management can be real-time transferred to production floor. The production process of textile industry is analyzed by this paper. Considering the technical advantages of RFID, the model of real-time manufacturing execution system based on RFID and perfection system solution is presented by this paper.

Study and Design Real-Time Manufacturing Execution System Based on RFID

From the supply chain, now RFID technology is gradually applied to the core of manufacturing process. By adopting the RFID technology in workshop layer, the exact real-time information that is obtained from RFID, can be seamlessly integrated into the manufacturing execution system. Therefore it can create additional value, and increase productivity for the enterprise. The technical advantages of applying RFID technology to the manufacturing execution system are analyzed detailedly by this paper. Taking the textile industry as object, the design of manufacturing execution system based on RFID is presented by this paper. And it provide perfection system solution for enterprise realizing real-time informatization.

Wind speed prediction based on multi-variable Capsnet-BILSTM-MOHHO for WPCCC

In order to compensate time-delay in the networked control system (NCS), the paper presents a state prediction control method which adopted time-stamp. At first, we studied a time-stamp based time-delay measuring algorithm of NCS and implemented the state prediction based time-delay compensation control to the system. Then, we proposed a state prediction control approach of establishing an approximate model to object states in the controller and actuator time-driven. With that, we designed a state prediction controller to make the system achieve prediction control and deduced the necessary and sufficient conditions for stabilizing the system. At last, the simulation results of the numerical example prove the validity of the proposed approach.

The paper presents a state prediction controller design method for networked control system (NCS) to compensate time-delay in the control loop based on the time-stamp information carried by the message in control network. At first, we study a time-stamp based algorithm of measuring the time-delay in NCS and apply the state prediction based time-delay compensation control to the system. Then, we propose a state prediction control approach of establishing an approximate model to object states in the controller and actuator time-driven. And, the necessary and sufficient conditions for stabilizing the system are deduced. At last, a numerical example and its state curve of prediction controller prove the validity of the given design method.
