在传染病动力学模型中,对疾病发生率的估计是传染病流行趋势预测和预防工作的重要部分。本文研究了一类非线性观测器在传染病动力学模型中的应用,利用非线性观测器估计疾病的发生率和传染率系数,并通过数值仿真验证了以上这些结论。关键词 传染病模型;非线性观测器;参数估计;自适应控制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.Key words:Infectious Disease Model;Nonlinear Observer;Estimating Parameters;Adaptive Control
