The Simulink simulation model of feed drive system of the doubleroller clamping spinning device driven by multiple AC servo motor was established in MATLAB/Simulink, including the mathematical model of the threeloop control. The current loop gain and speed loop gain were set. The mechanical system established in ADAMS was output to the Simulink platform of MATLAB. The electromechanical co-simulation of the doubleroller clamping spinning device was developed and the optimization of the control system parameters were discussed.
