How to find rough value of motor transfer
function
(1) Finding KM
Plot the relation between the motor drive current and tacho-
generator frequency to obtain the inclination.
(2) Finding
ωM
Though
ωM is found by measuring the motor frequency response,
this method generally takes a lot of time and labor. Measurement
of step response can find rough values easily.
Supply step-shape current to the motor in static status, measure
time
τM until the motor speed reaches 63% of the final speed and
then find
ωM by the following formula.
ωM = τ
