Fundamental Studies in System Identification

要运行一个动态系统，如化学加工厂或经济系统，需要两件事：描述系统的方程；调节系统以提供所需结果的方法。系统辨识提供了第一个；控制工程设计提供了第二个。这项建议涉及系统识别和控制中的三个重要问题。首先，由于方程永远不可能被精确知道，我们的目标是确定一个方程能做的最好的事情是什么？其次为控制设计提供严格的误差界； 第三，针对系统辨识中一些尚未解决的问题，开发新的方法。

To operate a dynamic system such as a chemical process plant or an economy one needs two things; the equations describing the system; a way of regulating the system to provide desired outcomes. System identification provides the first; control engineering design provides the second. This proposal addresses three important problems in system identification and control. Firstly since the equations can never be known precisely we aim to determine what is the best one can do? Secondly to provide then tight error bounds for the control design; thirdly to develop new methods for some hitherto unresolved problems in system identification.
