LQG of a Control system

Hi, I am trying to develop both LQR and LQG controller for my system. I am using LQG function, it gives me some A,B, C and D values. Are these values are my overall systems parameter or only the controllers parameter? How to use those parameters to see the overall states response using functions like lsim? Does lqg function automatically uses Kalman stater estimation? If not whats the alternative way to incorporate Kalman filtering?

Thanks in advance

Hi,

have you already tried to look up the documentation for finding some help concerning your problems? You can open it by typing the command:

doc lqg 
doc lqr
doc lsim

etc in your command window. As far as I see, the documentation should help you with at least half of your questions, maybe more, if you have a closer look. If you still need help afterwards I can try to help you.

Cheers,

Wine
