【摘要】 热工系统的动态特性在许多情况下很难用明确的数学模型来表达,而系统的数学模型在自动控制的分析、设计和综合中又占有重要的地位。首先论述了热工过程系统辨识的一般方法和步骤及其MATLAB实现方式;针对热工过程中普遍存在的非线性环节,更进一步介绍了神经网络在非线性系统中的应用,并给出了相对直观的MATLAB实现方法。更多还原

【Abstract】 It is difficult to describe the dynamic performances of thermal process with precise mathematical models, but the mathematical models play the crucial role in the process of analysis, design and synthesis for thermal control. The most common methods and steps for the identification of thermal process, together with their implementation in MATLAB, are given firstly. Contraposing the nonlinear process, the applications of neutral network in system identification are presented, and how they can be easily implemented in MATLAB.更多还原
