Rolling Mill Torsional Vibration Suppression Strategy Based on Improved State Observer

A multiple adaptive linear neuron(ADALINE)algorithm improved the state observer was presented.In order to overcome the problems that the elastic connection shaft triggers the torsional vibration of the main drive system and rolling mill system parameters are not easy to measure,first,the observer proposed can improve the observation accuracy by updating the weight coefficient online,and has high adaptability accurately not to need realtime measurement,then,the integral state was introduced,and the additional feedback was increasted to reduce the impact of the interference torque and reduce the cost.The design of the synchronization controller at the acceleration level reduced the adjustment time.Finally,the simulation was verified in the wide range.Analyzed the influence of feedback coefficient on motor speed and compared with the ADALINE speed controller,in terms of amplitude control and reduce the adjusting time all have good effect.The vibration amplitude of the motor was reduced by 37.31%and the adjustment time was 0.37 s.
