| 摘 要： | 化学组分浓度大于零以及反应釜的进料温度和浓度等在给定范围内波动对估计问题来说是以约束形式出现的附加已知信息.本文基于预测控制的滚动优化原理,讨论了一种能利用这些已知约束信息来提高估计的合理性与准确性的滚动时域估计方法.最后给出了对CSTR系统的仿真结果并与Kalman估计进行了比较.

| Abstract: | For the estimation problem of continuous stirred tank reactor (CSTR), some additional information such as positive concentrations and bounded temperature and concentration changes in feed are given in the form of constraints. In the framework of on-line moving horizon optimization, this paper discusses a moving horizon estimation approach that can make use of this additional knowledge to achieve an improvement in the estimation performance. Simulation results for a CSTR and comparison results with the Kalman estimator are discussed. |
