routh_t
ラウス表
呼び出し手順
r=routh_t(p) r=routh_t(h [,k])
パラメータ
- p
実数多項式
- h
実数 SISO 伝達システム
- k
実数多項式またはスカラー
- r
行列
説明
r=routh_t(p)
は
多項式h
のラウス表を計算します.
r=routh_t(h,k)
は,
ゲインk
によるフィードバックを有する
SISO伝達行列 h
で記述されたシステムの
分母のラウス表を計算します.
k=poly(0,'k')
の場合,ダミー変数k
で表した多項式行列でラウス表が記述されます.
例
s=%s; P=5*s^3-10*s^2+7*s+20; routh_t(P) //transfer function with formal feedback routh_t((1+s)/P,poly(0,'k')) // One of the coefficients in the polynomial equals zero P1=2*s^3-24*s+32; routh_t(P1) // A row full of zeros P2=s^4-6*s^3+10*s^2-6*s+9; routh_t(P2)
