精馏塔的H∞优化控制仿真

摘要

In this paper an optimal controller was designed for thedistillation based on H∞ control theory. As well, the distillation was simulated in closed loop. The simulation showed that when there existed disturbances H∞ controller could optimize and control the distillation better than LQR controller.%该文基于H∞控制理论对精馏塔设计了优化控制器，并进行了闭环仿真实验。仿真结果表明：当系统存在干扰时，H∞控制器比线性二次型最优调节器（LQR）使精馏塔实际达到的优化性能指标和综合控制指标都要好。
