Hopf bifurcation control for the main drive delay

2020-5-13 · In this work, the Hopf bifurcation of the main drive delay system of rolling mill is controlled and analyzed by designing a nonlinear controller. The time-delay is selected as a bifurcation parameter, and the following conclusions are obtained through analysis: (1) in the absence of state feedback control, the system will generate the Hopf bifurcation at the expense of its stability when the

Torsional Vibration Suppression Control in the Main

2007-6-1 · Abstract: In the rolling mill main drive system, a shaft torsional vibration is often generated when a motor and a roll are connected with a flexible shaft. The state feedback control can effective suppress the torsional vibration of the main drive system of rolling mill. Because of the difficulty of measuring the load speed and the shaft torque, moreover the sensitive of Luenberger observer
