According to the dynamic characteristics and static relationship of boiler steam temperature controlled object, to establish the model of boiler steam temperature, it can be described by block diagrams or state space, which has the full scope non-linear and time-varying characteristics. The section transfer functions can be converted into variable state space applied Jordan blocks and algebraic transformation...
Supercritical-pressure coal-burning unit has lower coal-consumption & polluter and higher technology advantage, but it also have non-linear and multi-coupling issues in process control. A practical mathematic model was presented in this paper in order to analyze the controlled object. Combined the simulation data and the real unit operating data several times, the model was modified to a higher...
Research of mathematical model is an important work in control field. According as the abstract concept of the Hammerstein model, this paper studies modelling method based on balance points of controlled object, taking objects of thermal control field as research background, establishes corresponding mathematical models of coordinate controlled object for boiler-turbine generator units whose boilers...
This paper presents a fast wireless anti-collision algorithm for radiofrequency identification (RFID) systems. The proposed algorithm introduces a new kind of inquiry round to gain the request prefixes from tags. It also has the advantages of jumping and dynamic searching algorithm (JDS) and prefix-randomized query-tree protocol (PRQT). Analysis and simulation results show that the proposed algorithm...
The research on mathematical model of coordinate control system (CCS) of boiler-turbine generator unit in thermal control field has achieved some significant results. But there are still some important theoretical and conceptual issues. And the correctness of every type of mathematical model has a direct effect on its practical application. Such as Bell- Astrom model, the controlled object described...
The validity of mathematical model as basis to research the boiler-turbine coordinated control system will direct impact the research result. Based on the energy conversation law, the Bell- Astrom model has deeply analyzed in this paper. The mathematical deducing offer a method applied to analyze and distinguish a mathematical model. Moreover it has provide that the mathematical model much more accord...
The multi-Agent modeling and simulating method of complex adaptive system (CAS) is one of the representative subjects for research in the field of complexity science. A framework for the multi-Agent modeling and simulating method of CAS is set up, which is based on the analysis of this method’s requirements. Aim at the deficiency exists in the agent rule learning and evolving based on genetic algorithm,...
