Purpose Generate stable random continuous test models
Syntax sys = rss(n)
sys = rss(n,p)
sys = rss(n,p,m)
sys = rss(n,p,m,s1,...,sn)
Description rss(n) produces a stable random n-th order model with one input and one
output and returns the model in the state-space object
sys.
rss(n,p) produces a random nth order stable model with one input and p
outputs, and rss(n,m,p) produces a random n-th order stable model with m
inputs and p outputs. The output sys is always a state-space model.
rss(n,p,m,s1,...,sn)produces an s1-by-...-by-sn array of random n-th
order stable state-space models with
m inputs and p outputs.
Use
tf, frd,orzpk to convert the state-space object sys to transfer function,
frequency response, or zero-pole-gain form.
Example Obtain a stable random continuous LTI model with three states, two inputs,
and two outputs by typing
sys = rss(3,2,2)
