Abstract :
The speed signal acquirement for the servo control system is a very important part. For the problem that in a low-speed movement, the differential signal of the position sensor cannot reflect the speed value of the servo control system, the paper proposes the digital filtering method of removing pulse moving average filtering to get rid of the measurement noise, based on the analysis and comparison about the analog filtering and the digital filtering. This method can not only successfully avoid the servo control system falling to lots of real-time online operation, but also is easy to turning in field, so it has the high theoretical and practical value.
