Gas flow relates to multi-information such as temperature, pressure, differential pressure in gas flow control system. A complete description of flow can be obtained by using ART2 network and BT network for secondary treatment of sensor data as temperature, pressure, differential sensor related to flow. And then a gas flow automation control program is proposed according to the prior description....
In this paper we present a formation synchronization and reconfiguration scheme based on distributed computation. In our previous work, we have introduced a formation abstraction by means of a virtual rectangular grid. The grid was used to ensure collision-free transitions between formations, coordinated by a centralized controller. This paper is an extension of that work, proposing control laws that...
This paper presents a command and control system implemented in Motru Hydro Power Plant. The system is an open system that allows further development of hardware and software, both the process and operating stations and in the communication system. System management is provided with the opportunity to connect to a higher level of supervision of the plant and monitoring SCADA systems in the central...
The main goal of this project is to develop and implement a prototype of two-axis solar tracking system based on a PIC microcontroller. The parabolic reflector or parabolic dish is constructed around two feed diameter to capture the sun's energy. The focus of the parabolic reflector is theoretically calculated down to an infinitesimally small point to get extremely high temperature. This two axis...
This paper modeled the disk brake automatic drilling system for the first time and pointed out its characteristics of high-order and time-varying, what's more, it is very sensitive to disturbance. A claasic linear time-invariant controller has insufficiently addressed deep and deviated directional drilling process from the control standpoint. herein, compound control strategies with computer including...
In this paper, a control method for making automated distributed management decisions is studied. And the consequences of externalized management on services and the system architecture is studied also. A simulation is performed to evaluate the suggested control method. The simulation results show that the automated manager needs 1) a system view classifying the current system state based on local...
Control system architectures are expanding significantly in terms of functionality, complexity and scalability. Real-time programming methodologies have evolved in the last decade with increasing complexity of control system and scalability of equipment in the industrial automation domain. The paper proffers an analytical survey of tools and methodologies that can enhance the control action simulation...
Due to the complexity of the self-propelled fire control system and the difficulty of test entrance's selection, the support vector machine combined with text categorization method (TC-SVM) is applied as the first step of fault diagnosis. The text pretreatment of text representation and feature extraction are introduced first. Then the error-correcting code is used to reduce the multiclass classifier...
Wireless communication technology, Internet technology, and standardized transducer interfaces are serving to shape the landscape of next-generation's remote distributed control system. The paper proposes originally to build the DMCS integration use of GPRS and Internet technology. Based on the analysis of function demands of the market for the measurement and control system, the thesis makes sure...
Autonomous underwater vehicle (AUV) has been widely used in marine exploration and military applications in the past decade. The Decision-making Control System of AUV plays a key role of accomplishing its tasks in complex undersea environment. In this work a Behavior-Based Reactive Decision-making Control System is proposed for AUV. During the design of the Decision-making Control system, the hierarchy...
Aim at the characteristics of maglev train operation, we present a control system for maglev traffic, and this system innovatively introduces electronic map-based control framework. We make a detailed discourse upon the key technology involved in this system (e.g. mode of data storage, centralized / distributed data storage and processing), and ultimately, not only establish the software framework...
The indoor test bed of the Autonomous Systems Laboratory has been used to create a control system for a small fixed pitch helicopter. This paper outlines the challenges posed by such a vehicle and the control system designed to overcome them. The control system utilized a visual tracking system to obtain state information without onboard hardware. Matlab/Simulink environment was used to facilitate...
The sophisticated computerized embroidery machine controller is urgently needed in embroidery industry. In this paper, we designed a kind of scheme with dual-core processor to implement its function. The controller can be divided into two parts, the host computer part takes S3C2410X as its core controller, it fulfills function of network, graphic user interface and etc through transplanting embedded...
Developing monitoring in Distributed Control System is a major industrial concern since those systems are more and more complex and involved in many safety critical application fields. The Distributed Control System (DCS) is being widely used in Power, Steel manufacturing, Oil and Gas, and Petrochemicals for monitoring, advance process control, regulatory and sequential control and various other functions...
One of the essential objectives of restorative control of urban power network (UPN) is to pick up the lost load as much and quickly as possible. The definition of restorative control of modern UPN is presented followed the explanation of the special characteristics of UPN. Then the multi-agent system (MAS) technology is introduced to establish the framework of restorative control. Several agents,...
Auto tuning PID controller is designed using MATLAB, Simulink and Graphical User Interface (GUI) as well as the optimization of PID controller without excessive mathematic calculations. Ziegler-Nichols second method is used for designing purpose of the auto tuning PID controller. Some drawbacks have been discovered using this technique, where in some cases analysis and design problems can be tedious,...
The Articulated Head (AH) is an artistic installation that consists of a LCD monitor mounted on an industrial robot arm (Fanuc LR Mate 200iC) displaying the head of a virtual human. It was conceived as the next step in the evolution of Embodied Conversational Agents (ECAs) transcending virtual reality into the physical space shared with the human interlocutor. Recently an attention module has been...
Auto-Dispensing machine is one kind of typical multiple spindle motion control system based on stepping motor. But the key point is that this kind of multiple spindle motion control system lies in position controlled by stepping motor, which also called spindle coordinate figure establishment. There are lots of coordinate figures should be input when dispensing machine work. In this paper, one typical...
Air supply flow directly affects proton exchange membrane fuel cells' (PEMFC) performance, when air supply flow exceeded PEMFC demands, lost of heat energy increased and power consumption of air-compressor increased too, so efficiency of generating current was reduced. Whereas, when air flow was under its demands, FC stack would be damaged with output power of PEMFC increasing in some extant. But...
