模型更新的两级自适应跟踪方法

Two-step Adaptive Follow-up Method for Model Renewal

讨论了经济管理领域中经常涉及的动态数学模型的更新问题，提出了一种模型更新的两级自适应跟踪方法．当系统环境发生突然变化时，这种方法可以及时修改模型参数，并使模型具有较高的精度．

Renewal of system dynamic model which is usually conisidered in economy and and management field is discussed. A two-step adaptive follow-up method for model renewal is presented. The method can modify model parameters in time and is of high accuracy while system environment changes rapidly.
