Question
A frequency response for the open loop system of a crane system is shown in Figure Q2.
a)
Analyse the transient response, stability and steady state error of the system, then
complete Table Q2.
Table Q2
Performance Criteria
Value
Transient Response
Phase margin, ØM
Gain margin, GM
Bandwidth, wgw =
Stability
The gain crossover frequency, woM
The phase crossover frequency, WGM
Stability* : Stable/Unstable/Marginally Stable
Steady state
Static error constant* : K„/K»/Ka =
Steady state error, ess(00) =
one answer only
b)
Re-evaluate the system performance if you are asked to adjust the preamplifier gain for
the system to operate at 10% overshoot.
(You should have another table similar to Table Q2 for the gain-adjusted system)
