系统辨识在空调房间建模上的应用

The application of system identification on air-conditioning room model

指出房间动态数学模型在控制系统中的重要性,简化了建立房间的理论数学模型,通过系统辨识的方法建立房间的模型,最后利用辨识的数学模型对阶跃响应的仿真结果和实测温度进行比较,从中可以选择所需精度的数学模型,进而考虑控制系统的设计和调节器参数的整定。

The importance of dynamic mathematic model in control system is indicated and the mathematic model of house is predigested, and then the model of house is set up by system identification method. The conclusion is drawn that the fit model can be gained after the step response simulation of different models compared with the measured temperature in practice, and selected mathematic model of the needed precision, and in addition the design of the control system and the parameter setting of adjuster can be considered.
