Speed Regulator T uneup: 2nd Order Responsewith Stiffness Filter
Calculate speed regulator gains based on 2nd order closed loop respon se 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 cr itically damped)
Speed Regulator Stiffness Filter
(stiffer value is larger and 1 produces a 2nd order response)
Speed Regulator Tracking Bandwidth in radians/sec
(bandwidth for coordin ated section so reference err ors are identical, practical
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 1st order response to a step input and a 2nd order response is given for a
Tracking Bandwidth of 0.
Speed Regulator Tu neup: Calculate SpeedRegulator Gains Command
This will perform the speed regulator gain calculations based on the previous
information of inertia, regulator mode, bandwidth, damping and stiffness.
