Abstract :
The authors propose a robust and fast speed control approach for a torsional system based on the state-space method. By choosing proper state feedback grains the torsional vibration is suppressed and dynamic characteristics are improved. A simplified model of the torsional system which is used to estimate the load torque is developed. Then the state observer of torsional torque and load speed is realized by using the model. The proposed approach is applied to experimental equipment. Both simulation and experimental results show the validity of the state observer. It is seen that the control system has fast speed response and robust stability
