| Abstract |
This paper proposes a new speed control method
using extended observer considering the effect of load torque.
The observer can estimate both speed and load torque, so the
effect of load torque on speed will be included and the accuracy
of estimated speed can be improved. In addition, using the
estimated load torque into feedforward loop, it can improve the
transient response and the robustness about the load
fluctuation. |
