摘要
本文采用两阶离散MIMO(Multi 1nput Multi Output)动态模型描述生化反应过程的动态行为,并以青霉素重复流加发酵为例,借助于计算机在线检测系统,在40,000L大罐上进行参数辨识与多变量自校正控制仿真研究。结果表明:该控制策略能够克服噪声和过程不确定性影响,使发酵沿最优轨迹进行,实现跟踪优化控制。
A second-order discrete MIMO (Mult Input Mult Output) model matching the industrial data is presented in this paper, With this model system identification and MIMO adaptive control of fed-batch penicillin fermentation is studied by means of one set of computer on-line sampling and measuring system. It is shown that the process can be controlled to a reference optimization trajectory by adaptive control law, This MIMO adaptive controller for fed-batch penicillin fermentation is more simple and easy to be put into operation.
