摘　　要：复杂系统数学模型的建立,采用传统的计算方法需要对整个系统的每个子系统进行详细的分析计算,往往需要耗费大量的时间;作者利用Lab VIEW与Matlab系统辨识工具箱对气动位置闭环控制系统进行模型参数辨识,得到复杂系统的数据模型,大大节省了系统数学模型建立的时间;作者对所建立的模型进行阶跃响应特性分析,从曲线可以看出辨识的模型能较好地实现阶跃响应,说明此方法建立的模型是有效的。The establishment of complex system model for math needs to adopt traditional calculating method to make a detailed study of the every sub-system of the whole system, which must take much time; Lab VIEW and Matlab are used to make an identification of pneumatic position closed-loop control system in terms of parameter model, and a complex systematic data model is attained, which saves much time to set up systematic math model; a step-response analysis is made of the features of the established model; and from the curve, we can see that the identified model can better serve the function of step response, proving that this method is effective.
