imrep2ss
state-space realization of an impulse response
Calling Sequence
[sl]=imrep2ss(v [,deg])
Arguments
- v
vector coefficients of impulse response,
v(:,k)
is the kth sample- deg
integer (order required)
- sl
syslin
list
Description
Impulse response to linear system conversion (one input).
v
must have an even number of columns.
Examples
s=poly(0,'s'); H=[1/(s+0.5);2/(s-0.4)] //strictly proper np=20;w=ldiv(H('num'),H('den'),np); rep=[w(1:np)';w(np+1:2*np)']; //The impulse response H1=ss2tf(imrep2ss(rep)) z=poly(0,'z'); H=(2*z^2-3.4*z+1.5)/(z^2-1.6*z+0.8) //Proper transfer function u=zeros(1,20);u(1)=1; rep=rtitr(H('num'),H('den'),u); //Impulse rep. // <=> rep=ldiv(H('num'),H('den'),20) w=z*imrep2ss(rep) //Realization with shifted impulse response // i.e strictly proper to proper H2=ss2tf(w);
