transfer function to descriptor

Calling Sequence

S=tf2des(G) S=tf2des(G,flag)

Arguments

G

linear system (syslin list) with possibly polynomial D matrix

flag

character string "withD"

S

list

Description

Transfer function to descriptor form: S=list('d',A,B,C,D,E)

Exdot = Ax+Bu y = Cx + D*u

Note that D=0 if the optional parameter flag="withD" is not given. Otherwise a maximal rank D matrix is returned in the fifth entry of the list S

Examples

s=poly(0,'s'); G=[1/(s-1),s;1,2/s^3]; S1=tf2des(G);des2tf(S1) S2=tf2des(G,"withD");des2tf(S2)
