This article presents an advanced speed filtering technique for servo drives independent from the system model information with the reduction of the performance tuning difficulty. The contributions are two-fold: (a) the first subsystem filters the rotor position from the encoder measurement to
recover the rotational speed of the rotor through the pole-zero cancellation technique, and (b) the second subsystem, which forms the disturbance
observer, attenuates the disturbance to improve the speed filtering accuracy. The prototype 500-W servo drive validates the improvement in filtering
performance under several load conditions.
