dsimul
dsimul — state space discrete time simulation
Calling sequence
y=dsimul(sl,u)
Parameters
| sl | : syslin list describing a discrete time linear system |
| u | : real matrix of appropriate dimension |
| y | : output of sl |
Description
Utility function.
If [A,B,C,D]=abcd(sl) and x0=sl('X0'), dsimul returns y=C*ltitr(A,B,u,x0)+D*u i.e.
the time response of sl to the input u.
sl is assumed to be in state space form (syslin list).
Examples
z=poly(0,'z');
h=(1-2*z)/(z^2-0.2*z+1);
sl=tf2ss(h);
u=zeros(1,20);u(1)=1;
x1=dsimul(sl,u) //Impulse response
u=ones(1,20);
x2=dsimul(sl,u); //Step response
