This paper introduces the application of Business Intelligence (BI) technologies in metallurgical manufacturing enterprises in China. It sets forth the development procedure and successful cases of BI in Shanghai Baoshan Iron & Steel Co., Ltd (Shanghai Basteel in short), and puts forward the methodology adaptable to the construction of BI systems in the metallurgical manufacturing enterprises...
For the problem of coupling in the variable speed refrigeration system, this paper proposes a dynamic feed forward decoupling control method Based on active disturbance rejection control (ADRC). Influence of the compressor frequency was regarded as disturbance of superheat control system, the variable speed compressor and electronic expansion valve ADRC controllers were designed. Comparison between...
Simulation training system can improve the trainer's ability, a rapid response and safety operating capability in the operation of real ship, to reduce operation accident of sailing. Intelligent examination scoring system uses the professional theory and practical experience as the evaluation criteria, and analyzes the operator's operation process to realize the automatic scoring through the program...
IN the domain of industry control, PID control is the basic algorithm, which has been used for a long time because of its simple structure, easy realization and many other virtues. For many simple control objects, PID control could easily achieve perfect effect, but for some complex object the effect is not so perfect. The submarine maneuver control system is a nonlinear six degree of freedom model,...
It is always a hard work to optimize the parameters of auto disturbance rejection controller (ADRC) because of its too many parameters. An optimization method for designing the submarine course ADRC based on the Nonlinear Control Design (NCD) block set of Matlab was proposed. The chief algorithm of ADRC and characters of the NCD block set were referred in briefly too. It was pointed out that there...
The warship operation training simulation system is developed based on the HLA (high level architecture), and the design approach of the simulation platform is given. The object model and federate proxy class is designed and the development process of the federation and its components is presented. It is proved in the simulation that the redundant data are greatly decreased in the communication network...
For meeting with diversity and speed ability of development of real-time simulation system, a method for developing simulation system based on Matlab/RTW is given. The simulation models are converted to transplantable embedded C++ codes by RTW, which can shorten the development time and reduce the development costs by combining Matlab with Visual C++. This method has been applied successfully in power...
In modern warship, many advanced power devices are equipped and they are generally complicated in operation. Work conditions of warship are numerous and variable, so it is very difficult to analyze the characteristic of its power devices. Models of main devices in some electrical propulsion warship are created, and simulation research is processed in different work conditions. It is proved that the...
