<strong>Observer</strong> <strong>design</strong> <strong>by</strong> <strong>pole</strong> <strong>placement</strong><br />
The condition e(t) → 0 as t → ∞ is a minimum requirement.<br />
In fact we want e(t) → 0 fast<br />
(possibly in a finite (small) number of steps deadbeat observer)<br />
The error dynamics is governed <strong>by</strong> the <strong>pole</strong>s of the matrix<br />
A o := A+LC<br />
so for desired error dynamics we can<br />
select desired <strong>pole</strong> locations of A o and choose L to achieve them.<br />
