摘要/Abstract

摘要： 针对常规工业系统建模存在的问题,提出一种基于稳态分量估计与状态跟踪的动态数据反向建模方法。该方法应用系统的动态数据,以数据末端系统输入值为输入的稳态分量并人为给定输出稳态分量,依据各稳态分量对建模数据进行处理后,将其分为三段,应用预估模型与状态观测器观测第一段数据末端的系统状态,并将其作为第二段数据对应的系统初态,第二段数据用来寻优预估模型参数及输出稳态分量,第三段数据用来验证模型。对某火电机组末级过热器进行建模,表明了该方法的有效性。

关键词: 稳态分量, 状态观测器, 动态数据, 反向建模

Abstract: Aiming at the existing problems of conventional industrial system modeling methods, a dynamic data reserved modeling method based on steady-state component estimation and state tracking is proposed. The dynamic response data of the system is selected as the modeling data. The input value at the end of the selected data is chosen as steady-state component, and the steady-state component value of output is artificial given. Steady-state component of the modeling data is removed according to the steady-state component of input and output, and the modeling data is divided into three sections. The prediction model and the state observer are used to observe the system state at the end of the first section, and the state is regarded as system initial state corresponding to second section. The second section is used to optimize model parameters and output steady-state component. The third section of data is adopted to validate the model. The finishing superheater modeling of a thermal power unit is carried out,and the simulation results show the method effectiveness.

Key words: steady-state component, state observer, dynamic data, reserved modeling
