自动控制原理一、稳定性第七章采样数据控制系统分析7.5 采样数据控制系统的性能分析首先分析 s 平面与 z 平面的映射关系。由 Z 变换的定义式知z = e Ts令 s=σ +jω , 代入上式有z( + )T σ jω σT jωTjθ= e = e e = z e
自动控制原理第七章采样数据控制系统分析于是得到 s 平面到 z 平面的基本映射关系式为zσT= e , θ =对于 s 平面上的虚轴 , σ =0 , s =jω , 映射到 z 平面上为zσT0TωT= e = e = 1, θ =ωTz=1ejωT平面上的虚轴 , 映射到 z 平面上为一个模为1、相角为 ωT 的复变量的轨迹。
