Transient response Flashcards
1
Q
How do we know if our system will have an oscillatory response?
A
oscillatory response arrises from a cplex conjugate pole pair
s = - ø ± jwd
2
Q
On a pole-zero map, how can we find second order system parameters?
A
Real part - rate of exponential decay (zeta x w0)
imaginary part - oscillation frequency (wd)
3
Q
How is the time response of a first order system determined?
A
K/ ts +1
K is steady state value
t is the time constant
1st order system has exponential approach to steady state
4
Q
Express oscillation frequency in terms of zeta and natural frequency
A
wd = √(1-z^2) + wo
5
Q
In terms of poles and zeros, when is a system unstable?
A
When the real part of the number is in the RHP
