化工过程的非线性内模控制策略（Ⅱ）─—发酵过程

The Nonlinear Internal Model Control Strategy for Chemical Processes(Ⅱ)---Fermenters

针对连续发酵过程，建立了基于非线性内模控制策略的调节器设计方法．当分别用稀释速率和加料基质浓度作为操作变量以控制产品产率时，通过仿真评价了所构成系统的品质指标．仿真实验结果表明，非线性内模控制策略可以用于发酵过程的控制，并具有良好的鲁棒性．

Controllers based on nonlinear internal model control strategy are designed for continuous fermenters.When the dilution rate and feed substrate concentration are selected as manipulated inputs for the productivity control,the performances of resulting system are evaluated by simulation. It is shown that nonlinear internal model control techniques areapplicable to the control of continuous fermenters and the good robustness can be obtained.
