The gear control of steel strand Bender is affected by many interference factors,such as load change,friction,temperature,etc. Therefore,a synchronous servo control method for the gears of steel strand Bender is proposed. To determine the control parameters of the steel strand bender gear,calculate the Jacobian matrix and determinant of the steel strand bender gear,and construct the synchronous control function of the steel strand bender gear used in the production of the wire,the optimal synchronous control value of the gear of steel strand Bender is obtained. The experimental results show that the control method has excellent servo control ability
