Aiming at the current situation that the dynamic load condition of transmission system is prominent during the operation of coal mining machine transmission system,which brings serious influence on the stable operation of coal mining machine,a dynamic load suppression scheme of coal mining machine cut-off transmission system based on self-resistant torque compensation is put forward,and the dynamic load fluctuation of coal mining machine transmission system is effectively suppressed by taking the difference of rotational speeds on both sides of the elastic shaft to be zero as the control target,and the compensating torque is increased on the basis of the electromagnetic torque control.By taking the zero speed difference between the two sides of the elastic shaft as the control target and adding the compensation torque on the basis of electromagnetic torque control,it achieves the effective suppression of the dynamic load fluctuation of the coal mining machine drive.According to the practical application,the control system can achieve effective suppression of dynamic load of coal mining machine drive system,which greatly improves the operation stability and safety of coal mining machine.
