基于催化重整装置反应器的非线性动态模型,将芳烃收率不可测变量扩展为系统的状态变量,构造状态观测器对其进行在线观测。鉴于系统工作点的不断变化特点来选取合适的反馈增益矩阵配置极点,设计了一种能在较大范围内稳定工作的自适应状态观测器。仿真结果表明,用该方法设计的观测器能较好收敛到状态真值。 Based on the nonlinear dynamic model of the catalytic reforming reactor, the unmeasurable variables of aromatic hydrocarbon yield were expanded to the state variables of the system, and the observer was constructed to observe it online. In view of the changing characteristics of the system operating point to select the appropriate poles of the feedback gain matrix configuration, an adaptive state observer that can work stably in a large area is designed. The simulation results show that the observer designed by this method can converge to the true state value well.
