| 摘 要： | 四水箱实验系统用于模拟实际工业系统的非线性、多变量、时变、耦合等复杂对象特性。基于系统辨识的结果,本文对该实验系统进行了关联分析,揭示了该实验系统关联度可调的特性,并分析了关联强度对多回路控制的影响。最后,本文应用基于前馈补偿的全解耦方法显著地提高了多变量关联系统的控制性能。

| Abstract: | The four-tank experimental system is used for emulating complicated object characteristics in industrial systems, e. g., non-linearity, multiple variables, time varying and coupling, etc. Based on the result of system recognition, incidence analysis is made for such system, The adjustable feature of incidence of the system is revealed, The influence of the incident degree on controlling muhiple loops is analyzed. In addition, by using fully decoupling method based on feed-forwarded compeusation, the control perfomance of multiple variable incidence svstem has been enhanced obviously. |
