| Abstract |
In the paper the problem of damping of torsional vibrations in high dynamic servo drives is presented. The time delays introduced into speed control loop due to digital control are modelled. A vibration damping method based on a vibration filter and a discrete-time sliding mode control is investigated in this paper. The vibration in the system is suppressed by a low pass filter within the disturbance compensation loop. Only a single position feedback device, on the motor side, is provided. The simulation results are presented to illustrate the achievable control performance of used scheme. |
