Difference Between Normal Feedback Controller and Robust Controller

Hi all,
If we misrepresent the Model of the system say we linearized the System Model or any parameter variations like friction, Temp etc.
Will normal feedback takes care of the offset of the Model?
I was confused with Robust Controller. What is it? and How effective is it than normal?

Thank You,
Yaswanth

Simple feedback does not necessarily mean a stable system, normally it doesn't, so you may (more than likely) need some sort of controller to compensate for system error.

What is meant by the term robust is that it can compensate the system adequately in different circumstances, anticipated and (perhaps) unanticipated, without a system hindering error (or just an error you can live with).

You should refrain from double posting. Check your post in the Mech Engineering forum.

Sorry about that. First I thought that it was Mechanical one and then after not getting any replies I post here.
