cls2dls

双線形変換

呼び出し手順

[sl1]=cls2dls(sl,T [,fp])

パラメータ

sl,sl1

線形システム (syslin リスト)

T

実数, サンプリング周期

fp

プリワープ周波数 (単位: Hz)

説明

sl=[A,B,C,D] (syslin リスト), 連続時間システム cls2dls は双線形変換s=(2/T)*(z-1)/(z+1) により得られたサンプル値システムを返します.

s=poly(0,'s');z=poly(0,'z');
sl=syslin('c',(s+1)/(s^2-5*s+2));  //Continuous-time system in transfer form
slss=tf2ss(sl);  //Now in state-space form
sl1=cls2dls(slss,0.2);  //sl1= output of cls2dls
sl1t=ss2tf(sl1) // Converts in transfer form
sl2=horner(sl,(2/0.2)*(z-1)/(z+1))   //Compare sl2 and sl1
