dc motor transfer function experimental
hi,
use frequeny genrator to supply squrare waves to the motor , after that use oscilliscope to plot the response of the output.
it can be clearly seen if the the motor is first,second or higher order.
if it is a first order system. used the 0.36V point to find out time constant T, and divde the output of the system by the input to work out the DC GAIN. K.
dont forget thtat the standard form of the first order system transfer function is
DC GAING(K)/1+Time contstant(T)
if the system is not first order system , then let you need to used another method to work out the damping ration,angular frequency.and the gain.
u need to do some reasearch about that. let me knwo if u r stuck with it though.
hope that helps
Kind regards
Mohamed
