Need your advice and support on different methods which we can try on the torque signal processing.

Hi guys,

Need your help.I have attached a short pdf about the description.We are trying to get the efficiency of the 3 phase asynchronous motor.The torque signals we are trying to filter for power measurement.We have tried low pass filter but we didn't succeed much on the accuracy part .The initial transient signal we plan to trim the signal.Need your advice and support on different methods which we can try on the torque signal processing.
