dscr(1) Scilab Function dscr(1)
NAME
dscr - discretization of linear system
CALLING SEQUENCE
[sld [,r]]=dscr(sl,dt [,m])
PARAMETERS
sl : syslin list containing [A,B,C,D].
dt : real number, sampling period
m : covariance of the input noise (continuous time)(default
value=0)
r : covariance of the output noise (discrete time) given if m is
given as input
sld : sampled (discrete-time) linear system, syslin list
DESCRIPTION
Discretization of linear system. sl is a continuous-time system:
dx/dt=A*x+B*u (+ noise).
sld is the discrete-time system obtained by sampling sl with the sampling
period dt.
EXAMPLE
s=poly(0,'s');
Sys=syslin('c',[1,1/(s+1);2*s/(s^2+2),1/s])
ss2tf(dscr(tf2ss(Sys),0.1))
SEE ALSO
syslin, flts, dsimul
