dscr

discretization of linear system

Calling Sequence

[sld [,r]]=dscr(sl,dt [,m])

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))
