摘　　要：系统辨识的关键是模型结构的辨识,它包括模型验前结构的假定和模型结构参数的确定。线性系统的模型结构辨识实质上就是确定模型的结构参数。该文以飞行器运动数学模型为研究对象,介绍了一种基于Bayes假设检验理论、适用于线性系统模型结构辨识的新方法,并给出了工程应用实例。The key to the system identification is the structure identification of the model, which includes assuming its prior structure and determining structure parameter. The structure identification of the model on the linear system is virtually to determine the structure parameter of the model. In this paper, the fighter movement mathematical models are taken as the research object;a new method on the structure identification of the model is introduced,which is based on Bayes theory and suitable for the linear system. Finally, an actual example of engineering application is given.
