Speed Regulator Tuneup: 2nd Order Response
with Stiffness Filter
with Stiffness Filter
Calculate speed regulator gains based on 2
nd
order closed loop response and set the
speed feedback filter to 10 times the bandwidth.
•
Speed Regulator Bandwidth in radians/sec
•
Speed Regulator Damping Ratio
(value of 1 is critically damped)
•
Speed Regulator Stiffness Filter
(stiffer value is larger and 1 produces a 2
nd
order response)
•
Speed Regulator Tracking Bandwidth in radians/sec
(bandwidth for coordinated section so reference errors are identical, practical
limits are ω/2d to 2ω, where 0 is unused)
limits are ω/2d to 2ω, where 0 is unused)
Note If Tracking Bandwidth is equal to Regulator Bandwidth the speed regulator
will give a 1
will give a 1
st
order response to a step input and a 2
nd
order response is given for a
Tracking Bandwidth of 0.
