自动控制原理第七章采样数据控制系统分析证明 : 根据 Z 变换定义Z∞∞± aT ± akT − k aT − k[()e et ] = ∑ekT ( )e z = ∑mekT ( )(e z )k= 0 k=0令zm=aT1ze, 则∞Z1 1k=0± aT k aT−m[ et ( )e ] = ∑ekT ( )( z ) = Ez ( ) =Ez( e )
自动控制原理第七章采样数据控制系统分析例利用复数位移定理计算函数 e at sinω t 的 Z变换。解 : 由 Z 变换表查得 sinω t 的 Z 变换为zsinωTZ [sin ωt]=2z − 2zcosωT+ 1由复数定理 , 得aT−aTzesinωTZ [e sin ωt]=2 2aTaTz e − 2ze cosωT+ 1=-at−aTzesinωT−aTz − 2e z cosωT+ e2 −2aT
