Torsional Vibration Control of the Main Drive System of a Rolling Mill Based on an Extended State Observer and Linear Quadratic Control

摘要: In the main drive system of a rolling mill, shaft torsional vibration is often generated when motor and roll are connected with flexible shaft. State feedback control can effectively suppress mill. Because difficulty measuring load speed torque, moreover sensitivity Luenberger observer to model uncertainties noise include in detected signal, this paper, we propose an extended state (ESO), new observer, estimate unknown states torque disturbance. We ESO linear quadratic (LQ) based controller integrator feedforward compensation for suppression two-mass The simulation results show improves performances command following, suppression, robustness parameter variation. This first ti...
