Speed Regulator T uneup: 2nd Order Responsewith Stiffness FilterCalculate 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 CommandThis will perform the speed regulator gain calculations based on the previous
information of inertia, regulator mode, bandwidth, damping and stiffness.
