自动控制原理第七章采样数据控制系统分析例试用实数位移定理 , 计算延迟一个采样周期的指数函数 e -(t-T) 的 Z 变换。解 : 根据实数位移定理Z从 Z 变换表中查得式得Z( ) 1[e − a t − TaT] = z− Z[e − ]Z−atz[e ] =z − e−aT, 代入上−a( t−T) −1 z 1= z =−aT−aT[e ]z−ez−e
自动控制原理3. 复数位移定理第七章采样数据控制系统分析若已知 e(t) 的 Z 变换为 E(z), 则有Z± aTmaT[()e et ] = Ez (e )式中 a 为常数。复数位移定理是仿照拉氏变换的复数位移定理导出的 , 其含义是函数 e * (t) 乘以指数序列 e ±akT 的 Z 变换 , 就等于在 e * (t) 的 Z 变换表达式 E(z) 中 , 以 ze ±akT 取代原算子 z。
