1.单位阶跃函数:用ε(t)表示,也可用1(t)、 U(t)表示

Production of Ab and Activation of Macrophages and Cytotoxic T Cells T-Dependent T-Independent

1.单位阶跃函数:用ε(t)表示,也可用1(t)、 U(t)表示

一、换路定则: 换路前瞬间记为t=0 换路时刻t=0 换路后瞬间t=0

设系统传函为G(s),则C(s)=G(s)R(s) r(t)=(t),(s)=1时 (s)=G(S)R()=G() ∴g(t)=[c(s)=

给定S3=S3(t),一个独立参数1=01(t唯一确定,该机构仅需要一个 独立参数。若仅给定θ1=θ1(t),则θ2、03、4均不能唯一确定。若同时给 定θ1和θ4,则3、02能唯一确定,该机构需要两个独立参数

System parameters are contained in,(t) and(t) Desired output is generated by taking the signal through the desired operator. The difference between the actual output and the desired output is the error, whose mean squared value we want to minimize We require a stable and realizable system. The error e(t) is given by:
