摘要
从飞机空调的温度控制系统设计的需要出发，首先用理论推导的方法求得涡轮冷却器的动态数学模型的结构形式，然后提出不用理论推导的方法求得涡轮冷却器动态数学模型的模型参数，而用辨识实验的方法求得涡轮冷却器的动态数学模型的模型参数。还推导了辨识的计算公式，论述了辨识实验的方法、步骤和结果。最后提出了涡轮冷却器动态特性的计算方法，并且以欧拉法为例论述了涡轮冷却器动态特性计算的具体公式和步骤。
From the needs of temperature control system design of air conditioning in airplane,firstly,the structural form of dynamic mathematical model for a turbo-cooler is derived theoretically. Then to make the dynamic mathematical model of turbo-cooler conform with the actual turbo-cooler,a way to get the model parameters of dynamic mathematical model of turbo-cooler by experimental identification instead of the theorectical derivation is proposed in this paper. In the paper it is also deduced the calculating formulas of identification and the method,process and conclusion for the identification experiment are also destribed herewith. In the end it is pointed out that the calculation method for the dynamic characteristics of turbo-cooler is presented in detail with an example by use of Euler's method.
