Abstract: |
Recently, it is proved in the literature that for a given
controllable pair (A,B) with A∈Rn*n,
B∈Rn*m, and any λ≥1,a gain
matrix K can be designed so that ‖e(A+BK)t‖≤MλLe-λt,where M and L are constants
independent of λ.Here, we show that M and L can be
chosen much smaller than that proposed above. As a consequence, the
estimation on overshoot of a transition matrix can be bounded more
precisely. This can be regarded as a complement to the existing
result. |
