tf2ss - transfer to state-space

Calling Sequence

sl=tf2ss(h [,tol])

Parameters

• h : rational matrix
• tol : may be the constant rtol or the 2 vector [rtol atol]
  • rtol :tolerance used when evaluating observability.
  • atol :absolute tolerance used when evaluating observability.
• sl : linear system ( syslin list sl=[A,B,C,D(s)] )

Description

transfer to state-space conversion:

h=C*(s*eye()-A)^-1*B+D(s)

Examples

s=poly(0,'s');
H=[2/s,(s+1)/(s^2-5)];
Sys=tf2ss(H)
clean(ss2tf(Sys))
