CCS/TMS320F28335: eQEP Speed Calculation in TMS320F28335

Part Number: TMS320F28335

Tool/software: Code Composer Studio

Sir,

We are doing a project on speed control of pmsm using tms320f28335 dsp with ccs v 6.0.0. The ti document "sensored foc of pmsm" is taken as reference. Increment level build 1 and 2 has been successfully completed. Our question is:

The encoder output from the motor is giving a varying speed, so its quite difficult to take it to further calculations. Can you suggest any measures to make the speed constant in open loop running of pmsm?
