There is a general phenomenon of dynamic disturbances caused by the mechanical resonance caused by the elasticity of the connecting device and the change of the load in the common electric traction mechanism such as rolling mill and robot joint. Aiming at this problem, the two - mass modeling of the rolling mill and other transmission equipment is carried out, and the related mechanism is analyzed. A combination of the fractional - order perturbation observer and the state observer is proposed to make the system have better performance to suppress the dynamic change. On this basis, the weight coefficient is introduced on the positive and negative feedback loop to solve the contradiction between the two constraints. It aims to improve the servo system response performance by adjusting the weight coefficient. In this paper, the resonant suppression function and anti - jamming capability of different weight coefficients are verified.
