摘要在系统辨识中，利用模型的物理特性是一种有效的方法。然而，如果要识别的系统太复杂，它是不可能的，以建立可用的物理模型进行控制。在这些情况下，构造简化的物理模型，但有时它们在性能上是不够的。本文提出了一种物理模型和误差模型相结合的辨识方法。首先，我们用一个简化的物理模型，以正常的方式识别一个系统，并定义一个误差系统，从它的估计误差。其次，我们辨识出误差系统，并通过补偿物理模型的误差来获得更精确的估计。将提出对内燃机的应用。
Abstract In system identification, it is worthful to utilize physical characteristics of models. However if systems to be identified are too complicated, it is impossible to construct the usable physical models for control. Simplified physical models are constructed in these cases, but sometimes they are insufficient in performance. In this paper an identification method using combination of physical model and error model is presented. Firstly, we identify a system using a simplified physical model in a normal way and define an error system from its estimation error. Next, we identify the error system and obtain more accurate estimation by compensating the error of the physical model. An application to an internal combustion engine will be presented.
