Torque signal from the transducer has lot of noise, How to get filtered signal with 1 % accuracy?

Hello All,

Need help on torque signal of asynchronous 3 phase motor. The torque signal has lot of noise. The motor was run at 170 Nm torque. I have used a low pass filter but the filtering is not so smooth yet. *

• From the frequency spectrum I have kept low pass stop band at 19 Hz. The filtered data is also for the reference which as 11 % accuracy. I am working to the accuracy of 1%. Need advice on the signal processing methods and suggestions.
