Identification of the Double Directions Control Model for Environmental-Economic System
环境-经济系统双向控制模型的辨识

According to the real conditions, the identification method of system model has been applied to a discussion on the identification of double directions control model for environmental-economic system, focused on the optimal control model in this model system, on the basis of the modelling thought of large system. Namely, an analysis is first made for the structure of a large system, then a resolution is carried out to turn the modelling of a whole system to the modelling of subsystems which may be easy to handle, and through setting up a series of cognate models, the whole model can be obtained. Finally the whole model is further simplified and its parameters are identified.
