摘要
精馏塔是化工生产中应用最广泛的操作单元.为了提高系统的整体控制性能,便于控制器参数设定,将塔顶与塔底组分间的关联关系进行解耦,利用MATLAB/NCD优化工具箱对PID控制器参数进行了整定,仿真实验表明了闭环系统具有良好的控制效果.
Distillation column is the most widely used operating unit in chemical industry. For the sake of enhancing the integrated control performance and facilitating the controller parameter tuning, interacting relation between the top and bottom product compositions is decoupled. NCD toolbox in MATLAB is used to optimize the PID parameters and simulation results demonstrate the validation of the proposed control scheme.
