dscr

Arguments

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.

Examples

s=poly(0,'s');
Sys=syslin('c',[1,1/(s+1);2*s/(s^2+2),1/s])
ss2tf(dscr(tf2ss(Sys),0.1))
