摘要：非线性系统最显著的多态特性往往受到操作条件的限制而不可能在开环系统中充分地被揭示,PI控制器的控制增益将增加了闭环系统调节的自由度,以此所揭示的非线性行为为模型识别提供了有力的依据,本文提供了全局分析的计算方法,并以催化反应模型来说明方法的应用。
The most distinct properities of nonlinear system is not fully revealled since the adjustable parameters are limited in physical and chemical properities. Degrees of freedom in controlled system will be increased and the corresponding controller gains can be adjusted freely. Revealled nonlinear behavoirs of the closed loop system under the conventional PID controller will be most effectively utilized for model identification and discrimination. In this work, this concept has been successfully applied to discriminate two rival models in N2O catalytic decomposition process.
