| | By the aid of Bristol-Shinsky method of multivariable control theory, this paper reveals that the controlled object of boiler follow control system possesses its own constitutional unstability. Compensation should be introduced to the structure of control system, that is, introduced a compensation net into it to change its constitutional characteristics, so that qualified coordination control system could be designed. | | 本文应用了多变量控制理论中的Btistol-Shinkey方法,揭示了炉跟机控制系统的控制对象本身存在着结构上的不稳定性.因此,首先必须对系统的结构加以补偿,即在系统中加入补偿网络以改变系统结构特性,这样才能正确地设计出合格的协调控制系统。 | | 文摘来源 | | Applying the general theory of the coordination control,the coordination control system of the imported 330MW turbogenerator unit is analysed. The rationality of this system is verified by the real-the simulation.Especially,when working in the BF mode,it is important to introduCe the non-linearity component with dead-time.A set of tuned controller parameters, especially the tuned feedforward compensation parameter are obtained through the experiment,which can be quo... | | 应用协调控制的一般原理,分析了引进型330MW机组协调控制系统。实时仿真试验结果表明,协调控制系统结构设计是基本合理的,其中锅炉跟随方式中带死区的非线性元件作用十分重要。通过仿真试验取得的控制器参数整定值,可供系统实际投运时参考,特别是前馈系统的整定值。 | | 文摘来源 | | Analyses the influent on the adjustment of deviation caused by the length stretching of product and radius changing of the drawing machine in the coordination control system and discusses the reasonable values of being fixed parameters.Designs circuits that are suitable for the coordinated control between the piston system and the speed loop of the motor in the line winder system in which the radius can not be determined on-line.These circuits are satisfied in practi... | | 分析了由活套形式构成的协调运行控制系统中因产品伸长和收线或放线半径变化对系统偏差调节过程的影响,论述了系统待定参数的合理值,并设计出能适应无法在线测取半径的收排线系统电动机转速环与活套之间的配合电路. | | 文摘来源 | |   | | << 更多相关文摘 |
