In this paper,in order to solve the nonlinear problem of backlash in gear drive system,a dual motor drive scheme has been proposed.This paper designed the coordinated control algorithm of dual motors,including torque linearization control algorithm and single speed loop speed feedback linearization control algorithm,which solved the backlash nonlinear problem in the process of motor gear transmission system movement.This paper first introduced the principle and control scheme of double motor.Then the control model of the dual motor system was established and analyzed.Finally,a simulation model was built to verify the control scheme.The simulation results showed that the dual motor control scheme proposed in this paper can effectively solve the problem of backlash nonlinearity in gear transmission.
