在傳染病動力學(xué)模型中，對疾病發(fā)生率的估計是傳染病流行趨勢預(yù)測和預(yù)防工作的
重要部分。本文研究了一類非線性觀測器在傳染病動力學(xué)模型中的應(yīng)用，利用非線性觀測器估計疾病的發(fā)生率和傳染率系數(shù)，并通過數(shù)值仿真驗證了以上這些結(jié)論。

Abstract：As for the infectious disease spreads trend estimate and the prevention work, it is the important part that the estimate of the disease incidence in the research of infectious disease dynamics model. This article studied the application of a nonlinear observer in the infectious disease dynamics model, made use of nonlinear observer to estimate epidemic incidence and infection rate coefficient. Finally, our theoretical results are confirmed by numerical simulations.
