摘要
文中以火力发电厂机炉协调多变量受控系统为研究背景,借鉴机理建模方法,给出单元机组被控对象的一种线性增量式集总参数数学模型,并应用状态空间法对其进行描述和分析,推导出输入和输出之间的传递函数矩阵,通过数学分析,导出其数学模型在结构方面的内在联系,从而对采用辨识方法建立单元机组被控对象的数学模型,提供一些重要的理论依据和设计概念。
Taking the multivariate boiler-turbine coordinated control system of the unit generator as study background, using the mechanism mathematical model for reference, one type of linear incremental congregate parameter mathematical model is given in this paper. And it is described and analyzed through the method of state–space, then the matrix of transfer function between input and output is deduced. Through mathematical analysis, some intrinsic connection in structure of this mathematical model is presented. So the theoretical foundation and conception of design is provided for the mathematical model of controlled object of unit generator obtained by system identification.
