Firstly, the discrete transfer function is expressed, and then it is transformed into the form of state space by ss:

& gt& gt？ z = TF(' z ')；

& gt& gt？ g=(2*z^2+z+2)/(z^3+6*z^2+ 1 1*z+6)

Transfer? Function:

2? z^2？ +? z？ +? 2

-

z^3？ +? 6? z^2？ +? 1 1? z？ +? six

Sampling? Time:? Unspecified

& gt& gt？ ss(G)
